89GP stalls, idles rough, hard to start

[valleydude]

I have an 89 Grand Prix and it has been running very crappy. It idles rough sometimes and:

1) When I go to a stop sign I have to put it in neutral and rev the engine so the car doesn't stall.

2) Sometimes the car loses power in the middle of driving

3) I have to give it gas for a while to start it and smoke comes out of the exhuast

4) The RPMs surge when idling

5) When I put it in drive after a complete stop there is a hesitation in power

6) The check engine light is always on and the oil indicator moves violently

What is wrong?

I was having the rough idle, stalling problem with my 89. machanic checked everything, including the computer. Turned out to be the Idle Air Control. Have your machanic check that.

pull you diagnostic codes, or go to your local autozone and have them run a diagnostic. that will help lead you in the right direction. also have the coolant temp. sensor checked
