Over the last few weeks, first got a code 45, (rich mixture) then missing and ignition cut-out after a few miles....after some junk yard parts swapping (MAP, O2, TPS, coil) with no improvements, finally found that the top bushing was wearing oval and the pick-up was going....for only $150...
Hasn't ran this good since I got it 3 years ago....(of course. a scope would have help the diagnosis)
YEE HAW!!!
