Dying in the street Camry...

[tturney]

1990 camry, 4cyl, autotrans.

had it tuned up...then it began to die on the street. it's intermittent. it's either starved for gas or spark. Repair shop replaced the air flow meter for $800 and it STILL did the same thing the next day...twice! I'm getting my money back if you can believe that! anyway...does anyone know why the car dies when trying to accelerate? if I din't know it was fuel injected, i'd swear it was the accelerator pump on the carb. it acts just like that! hesitation...then stall. or...hesitation then enough rpms to get it on. it does it when it's cold...then again just before normal operating temp. after that, it seems fine. anyone had this happen? what was the solution?

been dickin' with this for 3 weeks now!

maybe have your compression checked? could be old gaskets... i had a very similar problem with my 92, turned out to be a blown head gasket.

does the exhaust smell funny or are you getting a wierd color of smoke when the problem occurs?

thanks for a quick response. you've clued me in that i'd better add some details.
the head gasket is ok...and the compression is good and balanced. the car is not using oil...nor is it smoking or leaking. it runs strong (well...that's relative) when it's not dying! never dies when the rpms over 1300 (approx). it's that acceleration thing... again...just like an accelerator pump gone bad.

i don't think this alone could cause your isseus but it might be one of the factors.

Check your TB to make sure there isn't tons of carbon buildup there, and check the trottle cable while you're at it as well.

luisitol... TB???

would a clogged EGR contribute to the hesitation?

could it be the engine temp sensor?
did the car die while engine warm or cold?
if temp sensor malfunction,it will flood the engine with too much gas, and cus it to stall.

accelerator pump?????? whaaaaaaaat?

[CamryWhat?]

i would go with what Jwa said........... man it sounds like compression just because yopu can get it running and your car is idling all weird and stuff.....have some one check it out

[calvic]

its not your compression, don't piss your money away a compression check. Go back to the last thing you done to the engine. If it was running before the tune up obviously something was screwed up on your tune up ie: plugs, distributor, wires etc. If it was doing this before the tune up get a manual and a little low cost digital VOM and you can check out every sensor and FI related item on the engine.

good luck

did you find your problem having the same exact problem with a 1990 camry that i just purchased.

have checked out the coil and is ok. but what does this cold start
injector do have read that this may be a factor in the running
of the engine untill it reaches approx 113 deg f.

Ignition coil perhaps? They have a tendency to go on gen2's, and I rthink the symptoms of that parallel yours...

Im not sure about any of this, but i know a bad o2 sensor, could cause problems.... not sure if that could have anything to do with that....

emissions, if it idles kinda. Bet somebody else's bottomdollar.
Could be bad gas too.
