1990 Oldsmobile Cutlass • 6 cylinder •

I have a 1990 Oldsmobile Cutlass Ciera and I've been having problems on and off with it for a while now.

Here are the symptoms I have noticed so far:

-Vehicle vibration right after start up, but goes away after a few seconds

-Vehicle hesitation when gas is pressed until the engine warms up

-Engine knock/ping when accelerating and the engine is cold, it will stop after I have driven for a while

-Rough Idle after engine is hot

-Vehicle****** forward when I stop. Feels like some one is in front of the vehicle yanking on the front of the vehicle. This only happens after the vehicle has been driven for a while

How long since a tune-up? Any applicable mil codes? You can check those, yourself. Use a gage and check fuel pressure. Check the tps and iac, clean the throttle body.
