It all started at a stoplight one day rpm dropped I thought it was going to die the light turned green I gassed it and it was ok. It's gotten worse now it just dies. It seems to happen when the engine gets nice and warm. I drivee it to work in the morning no problem. The last two day's have been really hot and today was the worst day I had to leave it and walk home becaus it would not start up and stay on. rpms up then down almost up again then dead. It also will just lose power going down the road then get it back. Any ideas?

 

TPS is out of adjustment or a bad BAC valve, if it is happening once the car is running.

 

now it won't start . Previously it would be fine after sitting for awhile.

 

if it is not even turning over, you probably have a dead battery. If it turns over after sitting a while, you probably have a bad starter/starter solenoid

 

Sorry I said that wrong it is turning over but just won't run
