1987 Pontiac Grand am 2.5L Excessive Emissions, Poor Idle Quality
This baby is very rich. I did a test on everything I could think of but it all checkes out fine. I tried a new map sensor to be sure. The coolant sensor is working fine . Well, the new plugs are now black but ok I didn't run it long with them in. I AM STUMPED....
