Went to the track tonight for the first time on spray car was running great. Bolt-ons headers, exhaust,tune, 100 wet shot. br7efs gapped at .035. I went 11.89@117 and from there on got worse and I noticed my car was chugging so I called it a night and went home. On the way home my ses light came on for a misfire and the car was running like complete garbage. Im pulling the plugs tomorrow what should I look for? My oil looked good but I did notice my dipstick blew out some, I do not have a catch can.

Changed the spark plugs the drivers side were good but the passenger side were all black as night. I put new tr55s in since br7efs are order only from the stores around here. No I'm not spraying on these plus but i still have a misfire. Is this from running the tr55s with 4.5* of timing pulled?

Do a leak down test. Sounds like a ring land maybe.

Not a ring land. You have a bad o2 sensor on the passenger side. The new plugs are will foul again very shorty. Dave the old plugs too. All you need to do is put a wire brush on them to clean them up.

Bet its a o2 sensor on that side. Had a similar issue on my drivers side a while back.
