I got a bad misfire in my friends s-10 and can't narrow it down. I think it's one of his new wires not clicking in or a plug but there so hard to get at just can't pull them off and check. Is there a pid that can tell me what cylinder is mis-firing, all the misfire ones in efi live don't seem to work with his vechicle.

Misfire current, cylinder mode, 1-8 if it's an LS1; I have
no idea what this S-10 has for motor or control.

It's an 02 S-10. It has a 4.3 vortec in it but the controller pulls up as an ls1 controller in my efi live controller selection.

Check the distributor cap they are terrible on those motors. Also if it has alot of miles check the cam retard and adjust to +-3 deg by grinding the hole out on the dist hold down.

Found the problem his MSD wires don't know if the guy who put the headers on screwed them up but a couple of them were trashed.
