Hrm, maybe it's tps.



You're just jumping on a big whole injectors bandwagon. Hey, mike thinks its injectors so it HAS to be, dramon just isnt listening thats what it has to be. Finally, it won't cost just 135 to have injector's cleaned to get my injectors cleaned it'll all probably run me over 200 dollars at least. Everything i've done to this car has required me to get a crapload of extra parts and additional crap to get everything working.



And this is off topic but no FCD's arent cheap. Kevin keeps quoting this magical 20-30 dollars for a used FCD? Uhm, no BT74 offered 50 for his home made one and mike wanted 70 for his used one, yeah i don't see 20-30 in that at all maybe if you multiply it a few times? I'm not going to get a freaking FCD, its not worth my time its just gonna blow my engine if anything so instead i'm just gonna save up for a standalone.

Even if the injectors aren't the problem, they are still 15 years old and could use a cleaning/flow testing anyways.



Also, go ahead and check the tps first. If thats not it, then its injectors. I dont see the need for a new post about it but whatever that doesnt matter.

if you dont like the car....sell it



please take my name out of the post as this is not a problem about me....





you are just making posts to complain now...... i offered you a damn good price for my FCD... it is 107 new...i used it for 2 months....im asking 70 shipped



if you think a FCD will blow your engine...then you are certainly not up to par to work on your car....... a fcd will only remove fuel cut from your system .... the big pipe replacing your catalytic converters is what will blow your engine by running too much boost and going lean

youre right it wont cost 135 to clean them



http://www.rceng.com/service.htm#INJECTOR



according to them:



so it will cost a minimum of 96 and a max of 112 ....







research pays off!

you know you might actually have to go and start checking stuff on the car, you know like open the hood

I had to think long and hard before I posted this.



Have you read through the website for RC engineering or Marren Fuel injection? Do you realize that secondary injectors on our cars are not used that often, think of it like a set of twins on a FD, the secondary turbo locks up for most users because it is not used as often, I have a sheet here from the T2 I am buying that shows really bad flow rates from the injectors prior to Marren doing a cleaning on them.



they run 3 tests on them to check for the correct flow and spray pattern. The test results show 2 injectors being dirty, and a 12.8% difference in flow rates accross the injecotrs. After the cleaning one injector shows a slightly higher rate than the rest but are now all within 5.8% and flow more than they did originally. Will this be the only cause fo your hesitation, probably not, but does it hurt to have piece of mind?



another idea is the fuel filter, when was the last time it was changed, and what air filter is on the car, and when was it last changed?



There are a lot of things to check, do you feel a slight hesitation at the 3800 rpm crossover too?

I was told by the robot guy to avoid FCD's because they were bad. Then BDC said they might make me blow my engine because it alters the voltage so when i'm boosting 12 my engine thinks that i'm only boosting 8.5 and gives me fuel for 8.5. That is why i'm so against FCD's because i really odn't wanna blow my engine.



Secondly I do open my hood a lot. I check my fluids before and after EVERY time i take my car out. I finally fixed my coolant leak, it was the two coolant rings behind the LIM, not very fun to replace. That's another reason i am so sick of working on this car. I've had my intercooler/manifolds on and off at least once a week for the past month and a half and presently, it's just getting old considering it doesnt even work. It's like i'm taking everything apart only to put it back together and have to do the same thing again without any sort of result.



Finally, if what the FCD does isn't really as bad as BDC made it out to be, i'll buy urs mike.



thecamel: While i haven't read the stuff on that site what you said is pretty much dead on about them not being used etc. A local guy who also has a TII took all his stuff off when he fixed the same coolant leak that i had and he said that his secondaries were pretty clogged, so he swapped them with his primaries or something like that to clear them out. Oh, and i get the 3800 hesistation very very rarely.

Answer me this, why is it so hard for you to grasp a concept that people are reccomending? Getting the car to run right is a lot easier than continually avoiding the problem. A lot of the guys in here have already been in your shoes. Some of us are mechanics by trade. pay attention to what some of these folks ahve to say rather than going off on some tangent that does not fix your car at all.

apparently dramon only listens to thecamel.



Dramon did you skip my entire speech i wrote in your other topic? You have to take it step by step, if you cant handle it jump ship now.



chances are you have a multiple of thigns all building up into one big hesitation, if you work them away slowly one by oen it will be cheaper in the long run.



As for FCD's blowing your motor, they only blow your motor if you decide to overboost without proper fueling. what BDC told you is misleading, it isnt the FCD which causes a blown motor, it is overboosting without prior fuel setup which causes the blown motor.



kevin,.

the stock ecu never sees over fuel cut no matter what. fcd or no fcd. if theres no fcd, you hit fuel cut at 8.5psi (theoretically), so the ecu never sees above that, ever, period.



that being said, the fuel cut keeps you from boosting enough to pop the motor (12-13-14etc), because it stops runing at 8.5. unlike the fcd that will let the boost keep going until its too late

Kevin maybe he had you ignored...



Then he would indeed not see what you have written

he yelled at me and quoted my post in the same topic, he hasnt ignored me, he normally cmoes to me for advice, i waste time explaining things in details, he ignores it, asks "someone else" gets the same response and accepts it.



kevin.

Let me be the one to say that RX-7's suck!!! You have not even began to take the intake manifold on and off your car compared to how many times I have done it. One year I blew Three motors!!!! You either get used to doing it or get rid of the car. 2nd Generations get wierd problems like the ones you are seeing, other cars do not get those kinds of problems as often.



If you want to stop the water leaking from the LIM then Plug those holes on the Rotor housings and loose the water going to the Turbo then you can put a FD LIM gasket on it and never ever have to buy another gasket again. Problem Solved.



Take time and look at things......get someone more experienced than yourself to look at it. Even me when I am pissed off and tired of looking at my car I can't figure the problem... a friend says Hey isn't this supposed to go there?? or something like that Then I am like NO ****!!!

Everyone has the same problems you are having at one time or another. Sometimes we create our own problems when messing with the car This is all part of owning a Sports car that you want to make go faster. Its the same with driving it as well Crashing is part of the learning process. If you don't want any part of these things then find another hobby and accept the fact that its not for you!!! Or get rich and pay someone to fix you **** all the time.

there is a short article in turbo about fuel pumps and injectors, they

reccomend cleaning injectors every 70,000 miles or so.

rob obviously it cant be the injectors, everyone's been mentioning them to this kid for the past month, it so cant be the injectors.



oh wait his ecu said the injectors were the problem.



a dur to you dramon.



kevin.

it was actually RC that said this

why did you quote and correct yourself?



kevin.

instead of editing it



in other words, the people everyone is telling him to send his injectors

to get cleaned says to clean the injectors on a rotary every 70,000 because

the heat of the engine will varnish the injectors over time.

Since the earlier post got locked, I read the how to check error codes thing a few months ago and for some reason instead of the check engine light flashing i thought it was the clock that flashed. *shrugs* Anyways i'm gonna get my secondaries cleaned at least. The thing is a lot of times you read one thing somewhere and it's not right. A local guy said that the LED TPS checker thing doesnt work well, but i read that you can use that in every TPS FAQ i've read, one even said it was better than a multimeter. So, i decided to check it with the thing nonetheless, not that i was ignoring him its just taht i had the time and since i already had the LED thing, why not? Anyways LED thing said TPS was fine but i still have a TPS error code. Either way something is off *shrugs*. And, why should i sell my car? That makes no sense at all. It's the first car i've really been able to work on so i'm still learning, you don't know how good of an owner i am or i am not. The reason i haven't sent my injectors off and the reason i havent ordered this or that is that i HATE sending stuff out and i hate buying stuff over the internet.



And i unfortunately don't have the same kind of support that you guys have around town. There is one guy who i'm gonna take my car to hopefully sometime this next week and he's gonna look at it and check my TPS etc, but other than that there really arent and local 2nd gen owners. He's been one of two 2nd gen owners that i've actually met in my town. I can count on one hand the amount of 2nd gen's that i have seen around town. And i've had all my friend's and everyone else give their 0.02 cents on what's wrong. If all of them are right then pretty much every system in my car is about to fail.

everything will be ok

um welcome to owning an rx7?



if you dont count meets or at a shop i can count the number of fcs ive seen on one hand too.



its not like everytime i work on my car i call down a gang of 7 owners, i generally do all the work alone, in my garage, with the radio as my only entertainment.



kevin.

some people dont even have a garage, or electricity in the

garage, let alone a radio

Well, i'm beginning to realize that its just the RX-7 thing in general. Reading the forums and seeing problems without actually owning one i always thought it was because the RX-7's had been beaten on are were mainly problem RX-7s.



I love my car it's just i really didn't know how much work there was involved in maintaining it before i got it. In fact my TII is the first RX-7 that i've ever driven and I had only seen a girl start her 1990 GTU up but not drive it before i got it. I fell in love with the car without even driving or riding in a RX-7 before, its just I have at least 1k worth of stuff i want to get done to it but i only have 500 dollars or so right now so i'm overstressing myself out trying to make a budget.

so, i only work in the garage when the parts removable.



other then that i work on the blacktop.



i replaced my entire coolant system while it was snowing.



kevin.

were you wearing a outfit like this?
