Question some guided wisdom needed

I Am Having A Problem..... Ses Light Is Activated And When Having System Scanned, It Is Coming Up With A Misfire On Cylinder #6. Also, I Am Getting The Popping In The Exhaust When Backfiring And Have A Slight Hesitation. Drivability And Idle Are Still Good-managable For The Most Part. Just Recently Had Some Work Done On Car After The Warranty Had Expired. I Need Some Sound Advice To Remedy Problem. I Did Not Have Any Computer Tuning Done Yet. What About Plugs-wires Besides Tuning?

Welcome to the board.

Are you running aftermarket plug wires? First thing I'd do is make sure you don't have a loose or burnt plug wire on #6. My buddy has SLP headers and just had the same problem/symptom and found a burnt wire. Start the car in the dark and look for any arcing. #6 is the third one back on the passenger side looking from the front of the car. Hopefully it's something simple.

I'm still betting on the plug wire arching on the header somewhere as your problem. Coils should be fine, you'll get a lot of different opinions on plugs and wires - I went with NGK TR55's and Taylor wires - available from most of the sponsors.

Cool, glad that's what it was. I'd just pull that plug and clean it, and replace the wire. My buddy went with MSD wires and hasn't had a problem. Gotta love obdii and this site.

Don't forget to look into what caused the burnt wire so as to not have it reoccur again. If you have after market headers you might also want to invest in kool-sox (or similar) to protect the plug wires from the excessive heat of after market headers.

Oh yeah,,,,and make sure you don't touch that wire while the car is running. Those sparks may look pretty but they hurt like a SOB. LOL
