A week ago my car wouldn't start, or if I did get it to start, the moment I took my foot off the gas, it would die. I had the Idle Control Sensor changed, and it was fine. Then yesterday, the same thing happened...It would start but immediately die, I could only keep it running by accelerating high. I managed to get the car home, but when I pulled into the driveway the idle by then was so high I didn't even have to give it gas for it to move. I checked the fuel pump and that isn't the problem as the PSI was in the right range, and the other sensors are all checked. I hope I supplied enough info, do you have any suggestions that I can have checked?

Clean out the idle air control valve and test the throttle position sensor


Too fast an idle speed. If an engine without computerized idle speed control is idling too fast and refuses to come down to a normal idle speed despite your best efforts to back off the carburetor idle speed screw or air bypass adjustment screw (fuel injection), air is getting past the throttle somewhere. Common leak paths include the carburetor and throttle body gaskets, carburetor insulator spacers, intake manifold gaskets, and of course, any of the engine's vacuum fittings, hoses and accessories. It is even possible that leaky O-rings around the fuel injectors are allowing air to leak past the seals. Another overlooked item can be a worn throttle shaft and a defective idle speed speed control motor/valve stuck in the extended (high idle speed) position/throttle position sensor. Also the throttle plate could be binding in its bore and kinked accelerator cable, coolant temperature sensor might not be operating properly misleading the computer that the engine is still cold and computer throwing fuel at it raising the idle speed.

Thanks so much for the fast reply.....I am going to check everything you said and I will let you know the outcome.

Also, the idle ran high only one time, then it never happened again until I had the stalling problem. I had to rev the gas really high just to keep it running to get it home, luckily it didn't stall at red lights.

Well, it ended up being the PVC valve, it was clogged, and also a vacuum hose needs to be replaced. I appreciate your quick reply and excellent suggestions. thanks and I am sure I will be here again.

Thank you, we'll be waiting for you -The high idle problem is you have a vacumm leak and the computer sees it and compensating it

When I take the PCV valve off (the car runs without this piece), and replace it with the brand new part, it stalls again. It runs without it for some reason, but not with it.


I got it.....it was the temperature sensor.

You need to check out the entire PCV system.

Vent it-Lightly loosen the oil filler cap and see what happens
