Stalls and hard to start afterwards

SOURCE: Vibration when in gear, and stalling.

The problem is the torque converter solenoid. I had it happen on my 94 Cavalier a few years back and was a cheap fix at the local car mechanic. What happens is the transmission warms up and hits a certain speed where the solenoid engages, but then it sticks and won't disengage until it cools down sufficiently. When it sticks, it causes the car to shake when slowing down and will snub out the engine if you come to a stop.

SOURCE: car is hard to start, keeps stalling, white smoke coming out of tail pipe

It sounds to me like you have a head gasket leaking. See if you can get a gauge and check each cylinder. Are you using alot of anti freeze?

SOURCE: car won't start. turns over but stalls.

sounds like a fault in the theft deterrent

TCC Solenoid. Its locking up. Torque Converter Clutch Solenoid. Its a minor transmission issue. Have the same problem with my car.

Vacume leak or bad idle motor. With the car in park and running with the hood open listen for leaks moving your hand around the different hoses looking for a change in the sounds that you hear. The idel motor also makes the car idel up to 1500 RPM or so right at start-up then idel down, If it doesn;t the idel motor is likly. Check engine light is on when running? Test for codes, Follow code test charts don't skip any steps!.
