Runs jerky and won't stay running in drive?

I have a 1991 Toyota Camry LE. I am having trouble with it shutting off whenever I stop. It is hesitating to Idle whenever the accelerator is not pressed. What could be the problem?

I have had a mechanic check it before and I think he tried cleaning some component. I am not sure what.

I just changed my alternator for the second time and had my battery checked and it's great. But my car still keeps dying and I have no idea why. Help

We were told my 91 Camry needed a fuel pump. I replaced it, and the car starts and only runs for a few seconds. We also replaced the throttle position sensor. If we spray gas in air intake(?) It keeps running and sounds great. Sorry I'm not sure if thats what its called, I am winging this so my husband doesn't junk my car.

Thanks we unhooked the Map sensor, and started it. Went to a pull a parts place, and replaced it for 40.00, runs great now. The Shop that told me my engine was shot, even if they replaced my fuel pump, needs to quit their day job. My engine is great! Wasn't ready to give up on this car.

, putting on about 8k a year.

To start with I do a lot of maintenance on my car regularly. Particularly now that's it up there in age, I have had to change radiator, starter, water pump, belts, plugs, brakes etc. All have been replaced in the last few years.

In the last week, I have had my car stall twice in the same way, it happened when I am leaving a parking spot and I go in reverse to back out, apply brake to switch into drive, and as soon as I switch into drive my engine immediately turns off. I have to turn the key again to restart and it does so.

I have driven the car with O/D on and off and it switches just fine.

The transmission oil is fine both in amount and color. My oil was low which is odd because I just had that replaced a couple months back after I discovered an oil leak (repaired, timing, serptine, cram and crankshaft seals replaced additionally brakes pads, new tire, and alignment). I topped that off with slick 150 and now have the correct amount of oil.

I am wondering is this a pressure plate problem or what should I check next. The only other problem that could be connected is a occasional slight clunking noise when I shift from park to reverse.

There are no warning lights coming on.
Other than those 2 weird stalls, nothing has been abnormal in driving and I have been driving the car daily to work etc since this happened.

Recently swapped engines. Everything hooked back up except one grey connector near top of transaxle housing comes out of wiring harness near the starter. It is two leads and has a retainer clip. What is it?. And would it cause the engine to stall when you touch the accelerator? Can't give it gas at all.

I have had problems with my camry stalling after driving it for a while. I have got it towed to the shop and after it sits for a while the car starts. The mechanics cant find anything wrong with it. I have had work done to the electric windows, but they work fine now

My 1991 Toyota Camry has an issue with starting and when it is started, sometimes driving down the highway or even in town, it'll die out. I've been adding fuel injector cleaner as I believe that it's a fuel issue but the mechanics at the Toyota dealership will not believe me. I've had this car now for 14 years and know it quite well. The dealership put it on the diagnostic machine and stated that the engine ran perfectly. Of course it didn't "perform" for them as it does to me. I asked them to keep it a week and drive it around. An employee drove it around and it did it to him 5 times on the same day. They took it back onto the machines and said that they couldn't find a problem as the machine still checks out good. Well, I've been adding fuel injector cleaner every other fuel up and it runs fine since I've started doing this but I know that using fuel injector cleaner is not good for the rings and such. The mechanic refuses to change out the fuel injector stating that according to his readouts, it's not the problem. Can you guide me to resolve this issue before I have to have a ring job done and heaven knows what else? Thanks!

Go ahead and replace al wires with a new set.
Your problem is probably electric
