Ever since the cam swap I have been getting a P0300 code at idle only. If I idle for long enough it will set the MIL, but most of the time it stays pending because I don't idle for long periods of time.
I have also swapped PCM's but that was years ago and never got a P0300 until the cam swap. I have tried to do the CASE learn but it never works. I think it might be because my speedo will climb even when revving in neutral... And with the T56 swap it thinks it's in gear all the time.
I have changed the plugs, wires, coils, and checked for vacuum leaks.
The misfire PIDs show that it's misfiring about evenly on all cylinders at idle only. Off idle it does not misfire at all according to the misfire PIDs.
How can I use the scan tool and wideband to check for actual misfiring? Would it be an obvious drop in AFR? My idle AFR jumps around quite a bit. I'm idling at 700 RPM and 21 deg timing.
Since it's cammed, do I need to adjust the misfire tables? The cam is pretty small, 212/212 0.561/0.561 114LSA.
Thanks!
