I have a 1993 Saturn SL2. I replaced the EGR valve and since then every time i start the car the rpms rev up to 3000 for about 10 sec the go back down around 1000 rpm. Now, when engine is warm when you start it, it dies when put into drive. Have to restart and put in drive a couple of times before it stays running. Once it goes it runs fine. Any clues?

try the throttle position sensor

It could be a MAP sensor. Your rpms increase without giving gas. Also, your fuel compnents may be bad, giving improper fuel to the engine.

I would look at the egr system. First pull the valve and clean it. If you have a vacuum tester this would be a good time to test the valve itself as well. When under load you should be able to see the diaphragm engage and hold and then release as you release the vacuum. If that doesn't work check and/or replace the egr solenoid. It's located on the driver's side of the valve cover and usually runs about 60$.

Yours is a common complaint and the above is the most common remedy. Outside of that you might want to check and clean the idle air control valve and the port where it's housed. If it is extremely dirty or something managed to get stuck in there that could affect you vehicle running at idle as well.

Another thing, even though you just changed the plugs, pull one back out and look at it. If is fouled with oil you might need a new valve cover gasket which if it's leaking badly enough will impede spark.

My car was doing this pretty bad and I changed the engine coolant temp sensor and it fixed my problem. Hope this helps!!

Check the rubber hose the connects to the cover, it could be dry rotted from the heat and it just made it worse when you removed the cover. It could have cracks in it which you can not see. This is the only thing, unless one of the plug wires were damaged when you removed them.

Sounds like throttle positioning sensor.

a pit\ston might not be working properly

Hi. The EGR valve is a very sensitive issue. Buying a used one will always result in a continuing fault code. I recommend purchasing a new EGR valve. Before you install it, be sure to clean the EGR housing thoroughly. there can be carbon build inside where this valve is inserted. this carbon will trip the code if its not cleaned out properly.


please rate and god bless.

get it cleaned and rebuilt or get a new one man, and also check youre throttle cable
