Question about 2002 Pontiac Grand Prix
Smog says cataletyc not ready ,i have a new cataletyc convereter
Check the oil level, to much can ruin catalytic converter. Check O2 sensors with scanner, make sure they are work accurately. Check air box while car running, apply aceteline gas with no flame, recheck scanner for O2 sensors flucuatation. Compare all sensors for flucuation of 1mv to 9mv. If sensors flucuate they are good, if no flucuation sensors need to be changed. recommend to change cat with bad sensors. Before changing cat check for bad pressure.
