I have a 1995 cavalier with the 2.2L pushrod engine and it failed the emission test.
The hc emissions are a bit high .80 is the standard and mine is at 1.20 the co emissions are ok.
I have never had a problem getting a cavalier to pass i wonder what could be causing the high hc?
The car has new spark plugs and wires,air filter,cat converter,O2 sensor and pvc valve so it should pass with no problem.
Any ideas?
