What about one of those modules on the airbox?

I would rule out wiring probs since it's only at idle.

Default Swap POS's (Power Output Stages) on top of the airbox, see if the misfire moves...

even though they are new, just to be sure.

Do the misfires happen when cold, running temp or hot?

Hall sender on that bank of cylinders intermittent?

Cheers,

That would probably indicate a weak battery or a PC680 install.

Default Ah, but the engine load increases too when electrical loads increase. The alterantor can create

quite a bit of drag on the belt. The a/c uses the compressor, and further increases alt load with the compressor clutch, efk, and cabin blower motor.
His description of the problem is leading me to believe it's load related. Idle is usually less stable under the lightest loads and highest vacuum.

swapped, does not move. Looks like temp is not a factor. Not sure about your last?
