mine aren't as drastic as the first graph (like i said, at 6500 rpms...bank 1 will be .82ish and bank 2 .89ish) but I guess they are on their way out. Guess its time to replace them...thanks Doc

I found I had misfires in a couple of cylinders that all went away after replacing one coil pack

I can't recall... do bad O2 sensors throw a code/cel?? IIRC, the only way...

Confused after pulling some codes. EGT sensor or O2? <more>

Should I replace my O2 sensors, even if I'm not throwing codes?
