    Fourth Generation
    I’m admittedly stuck on this one. I have a 1994 base model for which I’ve just finished replacing the intake and valve cover gaskets. The vehicle just reached 100,000 miles, and has had no other major problems or repairs other than a replaced ignition module (approximately six months ago)...

    Engine
    Hi All, So I had a tick in the engine, did some research and the general consensus is that is probably either an exhaust leak or a lifter. Well I wanted headers anyway so I got some Doug's Tri-Y's and some flowmasters and they sound awesome but the tick remains unchanged so I will assume that...

  9. Please help with engine problem

    Engine
    I just got done putting my car back together after replacing my clutch. When I turned on the car it revved up and was running at a high idle and not very well. It sounded pretty bad. I am afraid it is the distributor because it is loose enough to turn by hand now. I tried to tighten the clamp...
