Krambo Posted January 18, 2005 Report Share Posted January 18, 2005 Well, I went for my inspection last week and failed. It was the OBDII type of testing where they plug in the diagnostic equipment let the computer do the rest. Here is the quick story: Made the appointment for the inspection and fearing that they would fail me for having the check engine light on, I went to Autozone and had the codes read and cleared. I had 3 P0300 (random cylinder misfires) and one P0742 (transmission - I'll post that one in the tranny section). I knew that I would have several P0300 codes due to the aftermarket cam so I didn't give it too much thought. Well, the damn OBDII saw that I had an engine code cleared and would not advance to the next test....FAILED! I told the inspector that I had 2 bad plug wires and replaced them and cleared the code (didn't want to tell him that I had a non-emmissions cam in the truck). He said that the truck computer will need to "reset" by itself which usually happens after 100-150 miles, at which time I can be reinspected and if there is no code, then I will pass. The problem is that I ALWAYS get the misfire code. It even came on while the truck was sitting at the inspection garage. It seems to trip at idle especially when the truck is not warmed up. My idle is around 700RPMs. Should I bump up the idle? Can I place a grommet under the gas pedal to increase the idle and avoid tracking down LS1 Edit and reprogramming? Any help would be greatly apreciated! Quote Link to comment Share on other sites More sharing options...
