2000 Oldsmobile Alero FAST IDLE, SHAKING AND DYING

Has the check engine light come on? Also, have you checked fuel pump pressure? Have you checked for vacuum leaks? EGR valve, IAC?

Glad to help. I would start by checking for vacuum leaks, fuel pressure, and then the IAC. The IAC is responsible for maintaining idle, so it is second only to a vacuum leak. Keep in mind, the EGR could be causing a vacuum leak.

Let me know what you find.

The gray smoke has me a little concerned. Did it go away? Has it come back?

Here are my concerns:

1) The gray smoke could simply be the result of a rich fuel mixture. However, a very rich mixture usually produces black smoke.

2) If the car sat for that long, it may have been condensation.

3) Where did you notice the smell coming from, under the hood or from the rear of the vehicle?

4) White smoke on start up usually indicates coolant getting into the combustion chamber and burning with the gas. Have you noticed that the coolant level is low or have you checked the oil to see if there is any creamy substance mixed in that would indicate coolant getting past the head gasket and into the engine?

Let me know.

Restart it and see if the smoke is white and check the coolant level.

Let me know what you find.

Let me know what you find. Also, have them check the coolant level as well as the oil.

Take care,
Joe

John,
