Hey there lately when im driving my rx my car seems to drive fine for a bit and then out of nowhere when it feels like it my car will bog out and lose power until I let off the pedel.





Now when it starts acting up like this which is totaly random by the way I have to very lightly feather the pedel to accelerate... One thing I noticed is I look over at my boost gauge (not stock) and it only has a hiccup and power loss when I get past 10 vac, although I let off the throttle and it will let me slowely feather it again but for some reason not past 10 vac.





Im starting to get frustrated becuase it does it at random times and will drive perfectly fine for a while and then start acting up again, a couple times it would bog out so bad that I would be reduced to driving 15km on main roads which is really aggrivating and I want to get to the bottom of this but need some possible suggestion. Thanks to anyone that can help.

check ur grounds thats probly your problem just searh for hesitation and youll get mad results and the sould be a write up

well I already did check my grounds except for the ecu ground so im gonna check that one out later when I have a minute at work.....





thanks

Mine of course being a NA is quite different, but I had a hesitation and grounded everything including the ecu and man what a difference with the vehicle, much better than before, I have to say I was shocked at the change

lemme guess, its at 3800rpm. if its around 3200rpm then you're looking at secondary injectors possibly being dirty/clogged/loose wires as thats around when they kick on.

No not exactly that would be too easy.....



its starts happening at any rpm and anytime it feels like it its not even close to 3000rpm. It usually starts doing it when I first start the car or after a short period of driving and doesnt allow to press the gas even the slightest bit over a light feathering. If i do press the gas more it doesnt respond at all just bogs and no response what so ever for the throttle until I let go and slightly feather it again but if I press just that little too much, total power loss.



So when my car is cold in the morning after 10 minutes of warming my car up I try to drive and some days it will respond others I cant even get it over 1500rpm with it completly losing power and bogging until I let off.... I could hardly leave my parking lot this morning, bogged hardcore down the street 100 meters and then pulled over waiting a little bit, popped the hood and tightened my throttle cable as it was a little loose and it started working again about another 100 meters down the road.



Im get really frustrated because I need to make it to work and I just cant get to the bottom of this.

check/adjust your TPS.

I just recenetly (2 months ago) had my tps set....



Could Me moving the throttle cable around messed with the tps?

if its not in the just right position the cable could be sticking, or getting pinched etc.

has to be in a perfectly smooth arc to the tb, no tight turns or tucking it between things.



kevin.

Its in the exact stock position so It should be fine....



But I had some time today and built a code tester and ran the codes and the throttle sensor code came up so there is something wrong with my TPS, I just find it strange how it comes and goes....

20-ish year old cars with most likely original parts tend to have a lot of those kinds of problems.



kevin.

yeah it ran good all day today so im just going to hope it doesnt happen again till I can have a look this weekend.

hmm, maybe a loose/poor connection. check the wires, make sure theyre not rubbing or falling out of the connector. bla bla bla



kevin.

that seriously sounds like a dead spot in the TPS resistor!!!! is it in the exact throttle position that it happens every time?.... you need a new tps sensor my friend... have that tps hooked up to an O-scope and watch it fall off at a certain throttle position... or if you are by chance running an afc, they have a built in o-scope... but its reaaaally reaaally slow so it will be harder to find on that but....

well with my great luck my car was stolen last weekend..... It was recovered however but bagged to **** , ran out of gas, and left on the side of the road.... thank god its all still there howver its acting up even more now...



The hesitations I was getting before come and go as they please, and its not so much at a certain rpm its after a certain amount of throttle being applied.





ALSO the car is very hard to start its as if its carberated, I have to pump the gas repeaditly to keep it running or else it starts up and immeadiatly dies out. I have to wait for it to fire up, the repaditly pump the gas to keep it going... usuallly dies out still the first few times then I get it going and have to keep it around 1500/2000rpm to keep it from dieing then after about a minute it will idle on it own....



Any suggestions would be lovely im losing my mind here lol

the hesitations is a bad tps... replace the tps..... as far as the hard to keep running check and make sure your not getting any false air ( vacuum leaks, or fresh air entering the engine after the MAF sensor) if it enters after the MAF sensor then its not helping to open the flapper door and the computer does not know how much fuel to spray...

Well it stoped hesitating now that I cleaned up some wiring however it starts reallly badly still.....



One thing I see that doesnt add up is there is a nipple right above the oil filter (closer to the firewall I think) that isnt connected to anything and seems to pull vaccum.



backfires like crazy when im trying to strat it aswell lol crazy gunshot sounds until it stays up and running and it seems as if the thermowax no longer works.
