SLP/Drew

OK a while ago I got some SLP longtube headers, and ever since then my ls1 has not been up to par. my car is an 02 ws6 with 16,000 miles on it and its been throwing this code left and right and my mechanics who work on it cant fiqure out why it keeps doing it.

Its the random misfire code and actually after i got my "bank error" corrected with my cpu the car has ran fine for the next few months and just today the service engine soon light came on PLZ HELP!!!

POST PLZ if you have questions or idea's on why it keeps throwing the random misfire code, and what the heck i can do to fix it

Here is a few idea's to look at.
plug wire loose
air leak near 02's
loose wire on coil.

I could figure it out in no time with a scanner to moniter the cylinders

checked the loose plug wire and i thought that their were no o2 sensors when I got my headers installed, and im not sure about the loose wire on coil but this has been a repeating pattern no one can seem to help, every time we pull up codes it says random misfire

Yea but with a scanner or EFILive you can read the mis-fire counts for each individual cylinder. This will help you zero in on the problem cylinder.

If there are no O2 sensors on your car, that's a problem you'll need fixed.

Make sure your plug wires are on there GOOD. One click for plugs, and TWO clicks for coil packs. This caused me some grief.
