I was driving on the highway at 65 mph. Then I sudenly accelerated to get through some traffic. After i got off the highway and got to a stop, the car started to vibrate on idle. It only vibrates on idle, if you accelerate, the engine feels fine and with force. The oil pressure gauge droped to around 17 psi. MY 88 GTA (350 5.7) was working perfectly before anything was wrong. I didn't want to move it anymore because i though it might be something more serious. What might be wrong? thanks

 

hard to diagnose over a computer screen but take a look att your tensioner and belt,also could be converter or flexplate then again the exhaust could've shiftedd touchiing the frame causiing it.try these first it might be something simple
