my mechanic loves to adjust my air fuel mixture..when he bumbs it it smells like gas..rocks up and down and trys to pull forward (feel in the engine feels like chuncks of something flowing through either the oil system or fuel system) and drinks gas

so I adjusted it got it right then the oil pressure gauge freaked out sometimes it would read right then other times it would read to high and I get a feeling it had that chunk feeling but not pulling forward or drinking gas...the idle would be normal and not bounce.

so I took it back on friday...he bumped it back up..I smell gas, pulls forward, and chunk feeling again.

I was told he adjusted it just a touch (well it took a good 3 inch turn to turn it back)

Is there a machine this can be hooked up to and set that idle right?

according to the CD I have the oil pressuge pump is bad but they dont think it is bad..

anyone with any ideas? beside sending the mechanic back to school?
