My engine stalls after driving for a while

I have a '94. With the exact same problem. I was just on this site double checking how to change my fuel filter when I ran across your question. Has anything you've tried fixed it?

I have a 1993 corolla with 223,000 miles on it. All original engine and transmission. I was wondering when my engine or tranny would die? I noticed that whenever I start it up from a cold start a white puff of smoke comes out of teh muffler. I think I may be burning oil or leaking oil from teh inside of teh engine. My engine also feels sluggish, I did a tune up and timing belt change at 200,000 miles. Is this condition dangerous or could it worsten? I.E. Engine blow up or breathing in bad fumes while driving, I am concerned since my wife is pregnant. I do not want to spend soo much on engine work butn let the corolla "die" Someone else told me to check my oil level and coolant level every now and then because white smoke means that moisture is leaking into the engine from the radiator causing irreversible harm to the pistons and head, valves, gaskets etc. I also had radiator and hoses replaced about a year ago at Sears so it may have not been a qualityy job either.

How did my head gasket get bad and how much you think it will cost me? Was I leaking oil or someone told me that moisture from the radiator was leaking into the engine. I am waiting for my engine to die adn drive it to the ground.

The car listed above (a-fe) quit running suddenly while being driven normally. Cranks but will not start. No spark, no fuel, strong battery. NO MIL light (check engine) and no codes stored. MIL light does not illuminate. Bulb is good. Mechanic said there was power to ECM but no output. Said it needed new ECM but could not warrant it. She cannot afford $1,300.00 replacement cost. No obvious damage to ECM or wiring. I can replace, but first I would like to verify that the ECM has failed. I have it out and have access to the connectors. It is not my car so I do not want to waste her money if it is not the ECM. Any ideas? Thanks.

Thanks Ken, I have ordered a used one. The mechanics she took it to are reliable and warned her that something else like a sensor shorted out may have caused the ECM to fail. That is why they could not warrant it. This is a 1993 OBD1. I do not see that happening but then again I have never had an ECM go bad. I know a lot of folks blame them but I find it is usually something simpler. Is there anything I should test before trying the used one? Also, where can I find a diagram for the connectors? I would like to jumper the power in to the MIL lamp out to confirm the mil lamp is working. The ECM is 89661-02090 engine is a 7A-FE. Thanks.

My friend is having problems with her car cutting off when it gets to operating temperature. She will crank it back up and it will idle badly then shut off. After it cools it will crank up and run fine for 15 mins. The distributer has been replaced twice. Could it be the EGR or a plugged catalytic converter?

Thanks for the quick response. I will check the suggested problems and give you an update. And, yes, the new distributor came with a new ignition module.

Hi tell your friend to use a scan tool to diagnose your coolant sensor any any other sensors. Replace those faulty
