A few years back,you could fool the CA emission computers if your car was "marginal"..all you had to do was stick a bad plug in..go test..fail...go home and install new plug and retest and PASS !! The computers at the time based retest(passing)results on percentage of improvement...think it took them a couple years to figure out what was going on...

I basically drove my 80 around got it hot after changing the oil...ofcourse...and I was able to pass the California emissions test...last week...it will make a difference..especially since you barely failed.
