So today I had a P0300 random/multiple misfire code come up. Again, I noticed this happened while the AC was running and had cycled on/off (can't remember which). The RPMs had also dipped.

106 is a test that needs adjusted in the tune to work within the limits or just disable the test

misfire with AC on you may have other issues now...check plugs and etc to make sure nothing is up with them

Well this misfire code is the first time it popped up since I had my knock sensors replaced about a year ago. But the idle does seem to dip some every time the AC cycles. It doesn't stay down but just dips for a second.

George, if you have EFILive I can send you a copy of my data log if you wanna look at what it's doing.

George C....

There's a air adder for AC clutch that will prevent dips

I don't use EFI live

Last time my truck had a misfire..somehow my blower sucked in a piece of paper pushed it thru intercooler and ended up on 2 electrodes of my plugs

It's under airflow for fans
