When the beater gets hot.(After driving 20 miles in 90^ temp) engine will lose power/not accelerate.



Gages: 13+ volts on Alt

Mid range on temp

60+ on Oil Temp



New Leading and trailing plugs

Cleaned Secondary Injectors

Punched out cats and replacement pipe



Car starts and idles at 1200, I have not checked the TPS



Any thoughts????

1200 is a fast idle, I would check and adjust the TPS, as well as the idle mixture, the idle, and the timing, all when the car is hot, just tune it by feel and see how it runs and starts, then see how it starts when its cold.

I would check you cats and see if they are clogged and glowing red, if you haven't alread gutted them.





And this is off topic, but do you want to buy my exhaust that I build John, there is pictures of it in this section, and it has spintech mufflers.





And if you don't know who this is, I am Cory that lives in Aiken. With the multi colored beater GTU.





Ohhh yeah and what is wrong with the RX-7 forum, is it messed up, I can't got there





Cory

read my post: I already punched out the cats

check for codes yet?



does the exhaust stink, as if its a hot mixture issue

the how bad is it? is it sudden? or gradual? the only ive seen like this is on a gsl-se, it was fast cold and it would gradually get slow to the point where top speed was like 30-40 mph. it turned out to be an aftermarket fuel filter that has rusted internally and clogged itself



mike

Comes on slowly as it gets hotter. If it sits 2 hours it is fine.



I am waiting on a care package from Mazdaformance with the filters and gaskets for a full bore tune-up. Along with the misc parts for the tranny swap

i think the fuel filter has a good chance of fixing it



mike

We shall see, If the pakage gets here b4 thursday night I will change it to see

Oooopps, I didn't see that.

Is there anyway that you can test your fuel pump motor??? I think it may be that, and it just needs to be replaced.

I had the same issue with the GSL-SE, the dude had put some stop leak in the radiator and it was clogging up at the thermostat. Flushed it and replaced the thermostat and it was fine after that.

I don't think that would cause the problem, unless maybe it was seriuosly over heating. But other than that your thermostat is closed when your engine is cold and it opens up when your engine heats up. And it sounds like your saying that since it was stuck close that it was bogging the engine threw the water pump. https://www.nopistons.com/forums/pub...1047683561.gif Is that why you think it was doing that??? Becasue that wouldn't do that.

Temp and Coolant flow are fine

Now with all the parts cars you have laying around, and I know the one I traded you has a good fuel pump, just take 20 minutes and swap another fuel pump into the car and see if that fixes it.

Care package from MAzdaformance arrived last night.



While removing the inlet hose to the fuel filter, a vile reddish brown substance started oozing out of the line...****!!!!! RUST!!!!!!!!.



Change fuel filter.



Move to rear of car, remove fuel pump, Sock is full of crud.



Make decision to use another fuel pump with NEW sock.



Start car up. Still has idle issues, but the 4K-5K stumble is gone https://www.nopistons.com/forums/pub...IR#>/smile.png





Based on the rust and crud in the tank I will replace the tank this weekend. I will also recirculate some OSPHO through the fuel line to flush out any rust crud.



The primary/secondary Injectors will also be pulled and sent out for cleaning

sucks, i think i gotta pull the gsl-se injectors and clean em too, leans out at high rpms



mike

Gives me a chance to find all the vac leaks.



Lets see whats on the Agenda this weekend:

1. Pull parts from Donor Car {Pedals, Mastercylinders, Harness and ECU}

2. Pull Steering Column, Pedal Cluster and Master Cylinders from Beater

3. Install Manual Parts in Beater

4. Pull Auto and Flexplate

5. Install Pilot bearing, flywheel and clutch

hahah, i have a wife to look after though https://www.nopistons.com/forums/pub...1047683664.gif

ever own a datsun? https://www.nopistons.com/forums/pub...1047683785.gif

no, but I owned a 87 323 that thought it was a datsun.

Allright..just got back from the shop,

Did a compression test. 95 PSI, good even bounces

Pulled the UIM, swapped the good clean secondaries in place of the primaries. Fixed the wiring to the alternator and replace the sheared stud for the CAS.



Car still idles like ****. Almost like 1 rotor isn't firing. not bad for 2 1/2 hours time. Will check the iginition and check the fuel system Friday. Still need to swap tanks

Datsun hell, have you ever owned a 1939 chevy truck. Well I have, and if I would have sand blasted it to get rid of rust there would have been nothing left. Other than a pile of sand and rust that is.

my friend had a 56 cadillac that we had to sweep under every day, while its on the lift



mike

Hahahaha..., this truck was the same way, every time you would hit it with anything, rust would fall off of it https://www.nopistons.com/forums/pub...O_DIR#>/11.gif



Damn I'm glad I sold that rust bucket. But then again I should have never bought it in the first place.

the 323 was like that, closing the door was considered a weight reduction so much rust would fall off.

Here is the cut open fuel? filter:

Close up

Gross!

Wait until you see the tank.

notice thats an aftermarket filter



mike

yep, looks like Autozone was the previous owners store of choice, Autozone battery, alternator, starter, belts, filters. Thank god for Mazdaformance

The latest. The top rad house had been replaced with a GENERIC convuluted hose, which was longer than stock. This caused the hose to rub against the AFM harness connection. MORONS!!!! Replaced with stock hose, Treated AFM connection with Stabilant 22.
