This sounds like the temp sending unit for the ecm is bad. There are 2 temp sensors, 1 for the light/gauge and 1 for the ecm. The sensor sends a signal to the ecm to tell it engine temp, the ecm them adjusts fuel mixture for cold or warm engine.This works much the same way as the choke does on a carb for cold starts

SOURCE: 2001 MAZDA TRIBUTE COLD STARTING PROBLEM

My wifes car had this same problem at about 100000 miles and after many trips to the shop it turned out to be carbor build up in the intake manifold. A fuel injector cleaner was hooked up and it helped the problem, but did not completely solve it. In oreder to get it totally clean the intake had to be removed and clean it out manually.

SOURCE: stalls when warm 95 camry

I had a problem with my 1995 Camry also. I would run fine cold, warm up when you let off the gas or shifted gears it would die. Sometimes it would start back up and sometimes it would not. After Many repairs, full tune up ect. ect. it turns out that the Coolant Temperature Sensor was bad. A $15 part. When you are driving the engine stays cool but once you let off the gas, when this sensor is bad, it reads the engine as hot and stalls it to keep it from overheating.

SOURCE: 93 chevy lumina euro won't stay running

sounds like it could be a fuel injector shorting out. have to get it hot, pull off the plenum and check the resistance in each injector. if any injector has bad resistance, replace it. when an injector shorts out on these particular vehicles, it shorts out the whole injection circuit. and when it cools off the resistance goes back up and it will run ok. i think the correct resistance should be about 13 ohms.

SOURCE: 97 cavalier starts and runs ok from a cold start after a few minutes of warm up it starts to run rough and miss. If i try to drive it it will start out ok but won't shift automaticly but shifts fine m

Sounds like possibly more than on problem, crankshaft position sensor, or ignition module likely on starting prob which maybe affecting shifting due to hard code in ecm, or shift prob could be shift solenoid in valve body of transmission. Both parts readily available from local parts store

Car won't stay running

If the problem only happens when the engine is cold, a bad electric sensor is likely to blame. If the car stalls even when the engine is warm, the cause is likely a faulty electric fuel pump.

Engine won't stay running when cold and a clicking sound comes from the engine and it surges. Once the engine has warmed up,it will stay idling but the engine races once put into gear(automatic)

Possibly an idle air motor for your idle problem or a vacuum hose off.

I own a 2001 Cadillac Deville. About a week ago, I ran out of gas. Once I refueled, it turns over but won't run unless I use starting fluid. And even then it won't stay running.

Won't shift when cold

With the car warmed up and running, check the transmission fluid level. It may be low or needs flushed.

2.0d x-type 2005 Est. Starting problems when engine is warm

Ok, time for car school. The vehicle is operated by the computer, every electrical concept that is. When the engine is cold, it starts fine because the computer has placed it in "cold start mode", putting more fuel into the engine than normally would until Once the engine is warmed up, a temperature sending unit or temp sensor tells the computer to change to normal run mode. IF said temp sensor is faulty and is not telling the computer to make said change, it stays in cold start mode, still dumping excess fuel in the engine that is now not required, cause it's warmed up. Like keeping the choke closed on older vehicles. Now I think you can answer your own question, when this no start action is happening after warm up and it always starts fine when cold, what's the first thing you check ? Right, the unsuspected temp sensor. Change that and no more start problem. Have a wonderful day. Glad I could be of service.
