Check for a major vacuum leak.
I would check coil, leads, and plugs.
you should check the steering wheel gasket first. if that's not it, then you should check the blinker fluid
Check your fuel pressure first then go from there.
it might be your throttle
There's a solinoid in the transmission.Suggest to check that first. Turn on interior lights. Start engine. If the lights go out when the engine stalls, you have a bad ignition switch.
When your car stalls when its raining, it may be getting water in the distributor cap. Make sure the cap is on properly.
It cold be either a plugged fuel filter or an electronic ignition component that is failing from heat stress.
There can be many reasons a car stalls from poor fuel feed to lack of spark. By far, the main reason is poor driving technique.
Check for vacuum leaks.
may not be the answer you are looking for....but, have you tried to check throttle position sensor?? and does the car have a check engine light on??
Check the torque converter lock-up solenoid. Disconnect it and if the problem goes away it is defective. You can drive the car with it disconnected but it will get poor mileage.
