90 Pontiac 6000

only have had car 2yrs. car was a Florida car,w/113,120 miles
Recently changed old air filer an noticed "oil" in the air canister. Is this a major problem? cause dont wanna spend lots of $$ to fix:eek7:
Also where can I find the following...idle speed spec due to idleing way to fast and fuel filter location. :confused: Thanx

Welcome to AF, post the engine size for help number 1. Oil in the intake can be caused by excess blowby or an inoperate pcv system. Most engines of that era do not have adjustable idlle controls.

They do have them but it is not supposed to be messed with, so unless someone else already did then you should get a Manual and follow the Minimum idle procedure. I dont know it off hand sorry.
