Actually, the guy I bought the car from pointed out a place at the exhaust manifold. Where the exhaust system meets the manifold, it looks like a screw is loose, a screw that the previous owner tightened. Is it normal to have a "farting" sound when driving, because to me it sounds like a leaking exhaust. I have a feeling that the sound comes from that place, because it seems to be coming from the engine bay.
About my mech, his workshop consists mostly of turbo charged 92 civics, but the pros are that you can get away with a 4 hour job for $150 bucks. <img src="/forums/images/graemlins/smile.gif" alt="" />
