94 camry hesitates at idle when warm - Toyota Nation Forum : Toyota Car and Truck Forums

I have a 94 Camry, V6. It starts great when it is cold, but after warmup it hesitates while in gear and at a stop and is very noticeable. At least once a week it doesn't even start at all after sitting for around 8 hours. I have spent over $2500.00 dollars in the past few months and the dealership doesn't know whats going on with the car. So hoping to get some help here. Any information will be helpful.

Can you tell us what the dealership has inspected/tested/replaced, other than your bank account?

New ox sensor, electrical system, fuel filter, plugs, ignition system, just about anything they could check or said they checked. They told us that they could not find the problem and when they took it out for a test drive they told me that it ran great. When I got it back and headed out on the road, not more than 15 minutes into the drive, it started the same hesitation at a stop sign and just last night after sitting for eight hours while I worked it wouldn't start, but started up this morning fine.

"New ox sensor, electrical system, fuel filter, plugs, ignition system"

What specifically do electrical system and ignition system mean? We understand your frustration, but you have to take a deep breath and be specific about what exactly was replaced, if people here are going to be able to help you. Refer back to your bills and let people here know the specifics of what was done.

You also have to be specific about what's happening when the car doesn't start. Does the engine crank (turn over) when you turn the key or does nothing happen? Do you hear any sound(s) when it doesn't start?

Did any of your bills show the idle air control valve was cleaned and/or did anyone inspect the engine coolant temperature sensor? Also check to see if they ever replaced the coil inside the distributor.

So it only has problems when warm and at a stop? If it was all around, I'd say vacuum leak, but wouldn't hurt to check anyways.
