pewter- 02 TA WS6
random engine misfire
I just installed pace setter long tube headers with an off-road y-pipe and O2 sims on my 02 ws6 and everything went together fine. But when I started up the car it sratred back firing like crazy and the SES light started flashing. I read the code and it said mulitple cylinder random misfire. and I have no clue what the hell is wrong. any help would be awesome.

are all of the plug wires completely pushed onto the coils and plugs? when you push the wire onto the coil, you'll hear two clicks. only one click when going onto the plug. some code readers will tell you exactly which cylinder it is.

^^^ Also go back and retrack all the basics....make sure the sims are only on the rear o2's, wires on the right plugs...etc

One thing that happene with mine is that I knocked the coolant temperature sensor off (broke it) while putting the headers on. It made my car run very rich when it was cold, and it would backfire some. The sensor is on the driver's side going into the side of the head, right above the very front of the header
