I have been trying to get my 1995 GSX to pass emissions. It is failing for HC (hydrocarbons) and CO (carbon monoxide). There is a slight misfire at idle (no MIL) and it runs rich once it gets into boost.
I have already checked the timing. I smoke tested the intercooler piping and intake (Fixed small leak). Replaced spark plugs NGK and wires. Did a compression test (140 for all cylinders). Replace O2 sensors.
Any suggestions on what to test next or what could be causing it?
I read all the other threads about this for 2-3 hours and did not find a solution that is why I am posting one specifically for my issue.
