3rd Generation Strange Stalling Problem on 93 Camry 4cyl - Updated

I am new here, hi everyone.

I have a 93 Camry LE, great car, relatively no problems. Recently, had some fluctuations in rpm while driving, and that eventually lead to stalling. One day, it stalled and would not start again and after a few minutes I got it going. Took it to my trusted local shop. Changed the plugs because they were pretty due, and they noticed that one of the spark plug wires was touching another cable which caused a reaction (carbon) to begin damaging the spark plug wire. We thought this was causing the interfence and was the problem. Continued to drive and things seemed fine for the most part. One day I stalled again, and then later in the day stalled again and could not get the car to start back up. Went back to the shop. They have had the car for several days, letting it run, driving it...trying to get it to heat up and reveal the problem. Nothing. It is giving them no problems. We cannot determine the cause. It could be the distributor, but I am not going to start guessing like that.

Anyone experienced anything like this or have any suggestions? I am not very knowledgable of cars, and explained it all the best I could.

Additional Notes:
- Stalls when coming to a stop, usually when stopped at a light. Does not do it initially, but after driving a while. Sometimes a couple weeks even. When it starts, usually happens in bunches.
- After several stalls when re-starting becomes difficult, turning, turning up AC on high, then cranking usually helps.

UPDATE: Replaced the ETC sensor about ten days ago, and took a short trip of about 150 out of town, and back the next. No stalling or any such problems thus far.

UPDATE: Approximately 600 miles with no stalling. Problem appears to be gone for the most part (at least the stalling).

09.08.05 Update: RPM bumps have gotten kindy goofy again, but no stalls yet. Something is probably still wrong, but as long as I don't stall out I can live with it.

I've had a similar problem... When do you stall? Slowing down? Or is it random?

Crap.... guess I'll change it later.

a few years ago, my 93 dx 4cyl had problem stalling when the engine was warm up, sometime i can start it, sometime i have to wait 5 or 10 minutes, left car at the toyota dealer and they let it run for whole day, and no problem, but once i took it back, it stall again at stop sight or traffic after engine warm up, then i brought it back and left it there for a week, and they finally found Engine Coolant Temperature sensor at fault, the malfunctioned sensor telling ecm the engine is always cold even after the engine was hot, and sending more fuel to engine, thus flooding and stalling the engine.
not sure yours is a similar problem

It stalls usually once I hit a light or I am going very slow. When I am driving along it just has fluctuations in the rpm.

Hmmm... My problem would randomly occur, and only when I was slowing down, like at intersections, stop lights, turning, etc. The engine would idle low then just die. I never found out exactly what the problem was, either. Eventually, it just went away and has yet to reappear.... *knock on wood*

I just did my first post and then did a search and found this thread. My car does the exact same thing. It's very random so no one can diagnose problem b/c it doesn't do it when I take it in to the shop. It just mechanics trying to guess.

Yep I did a tune up too in the beginning. Drove it again today. No problems. No stalling. Some think it might have to do with the weather. Seemed to die on hotter days. I am going to check out your troublshooting thread.

yah.. the real f'ed up part about it was after leaving it with a shop for the majority of the day when getting the tune up.. they couldnt figure out what was wrong.. i was the one that figured it out after researching on TN for other people having similar issues. it pretty much narrowed down to either the ECT sensor or the EGR valve. sure enough after disconnecting one of the vacuum hoses for the EGR valve my problem went away

go me

I have exactly the same problem and it's been doing it for quite a while that end up getting a 05 Corolla S. Anyway, I have a really bad experience with it that I took it to 3 repair shops including PEP boys that charged me $400 and did not fix the problem. But it works OK since I got my money back. But last week I decided to bring my 93 Camry to the dealership this time and their diagnostic is the Idle Control Valve or IAC that causing the RPM to fluatuate at about 2000 RPM and hesitate when running slow or dies at the light.

Try gradually increase your RPM and see what point does it fluatuate and also try cleaning the IAC since it's very expensive to replace this part. Cost about $220.

Good luck.

OK here is an update. I finally started driving the car again. For about two weeks I had no stalls or anything. Then one day it did, switched cars, went to my destination. Started driving my camry again for a few more weeks.

This past Thursday, it probably stalled three times in about 15 minutes. I also had trouble starting it when I left someplace. Next day, I drive to the outer banks. Going all over the place did about 400 miles this weekend. Stalling got crazy. Almost didn't make it home. However, what I have found out is that when it won't start, I go past accessories and turn the key where I can get AC power etc. I crank the AC up, and I am usually able to start the car. However, the last time I had to just let it sit for 15 minutes or so till it went. Of course after sitting a few days it starts fine. Started to take to my trusted local shop and they recommended this battery/electrical shop. That shop said he doesn't deal with engine related stuff, then recommended the same local shop that sent me there. Basically said if they won't do it I will probably have to go to a dealer. Any thoughts??? This is driving me crazy.

How does it stall? Does it stall when your coming to a stop light, when idle, or accelerating? I would suggest clean the TB and check your vacuum lines. Also, try what reddog69 suggest. He got his Camry to work fine after changing the EGR valve.
Let us know what you find out.
