Help! I have a miss! I have a 2002 Z28 m6. When I'm driving and accelerate it has a miss... It has only made the SES light come on one time under hard acceleration flashed a couple of minutes then went off and hasn't come back on.....I put new MSD wires and TR55 plugs last spring only a few thousand miles on them.... I cleaned my MAF no change..... I took it to advance and scanned it and it had the p0300 code but it also said oxygen sensor bank 1.... I have long tube headers and ORY with the rear O2 sensors deleted and tuned out.....would a bad O2 sensor cause this miss? Only happens under load.....doesn't miss just Erving the engine....
Thanks for any help!

No your O2 sensor is not bad, and would not cause a miss. What the o2 sensor is trying to tell you is that your problem exists on bank 1 of the engine, which is the driver side. At this point with limited information I would start by smoking the engine for vacuum leaks.
