Need help figuring out problem w/ my celica - 6G Celicas Forums

Topic #68112 8 posts Started by Smitty2145
Alright... I have been having problems with my car sputtering and stalling out on me for a few weeks now. This only happens after the car is brought up full running temp. When the engine is cold and i start it up.. it seems to run fine... I can drive it for a few miles... but then after i come to a stop sign and idle it has problems accelerating... it will start to sputter and sometimes it will stall out. most of the time it will start right back up... but sometimes i have to let the car sit for 5-10 mins before it will fire back up again.
Here is a list of the things that have been replaced withing the past 21 days

-Plugs
-plug wires
-dist. cap and rotor
-ECU
-thermostat
-a few of the vaccuum lines

I just ordered a new Vac. modulator and idle air control valve.... if anyone else has any suggestions please let me know... i love my car and it is really starting to piss me off that i can't drive it around reliably.
thnx

Fuel filter, bad gas, or a rusty gas tank biggrin.gif
It could also be the distributor
possible fuel pump, replace the relay as well.

I already replaced the fuel filter and it didn't seem to make any difference. The fuel pump is only a year old... so it should be working fine. Is there any way for me to test if my tps is working... resistance test or something?

would help if that info about the pump had been in the first post, longshot but replace the fuel pump relay for ****s and giggles. a bad pump can burn the relay and cause problems later.

Alright... my bad... i tottally forgot that i replaced the fuel filter already.
I'm waiting for my parts to come in ... so probably tomorrow i'll stop and get a relay and see if their is any difference.
I tried pulling codes on my car today.. and it said that their wasn't any stored codes.
Clean out your idle air control valve.
