Misfire on a Hemi
Hemi came in yesterday with an intermittent misfire on
cylinder 8- checked the misfire counter and could watch
misfires happening on the right bank consistently. Customer
informed me the truck had just had head gaskets at another
shop in town. I thought maybe the head was leaking and
checked the coolant for exhaust gases, but got nothing.
Pulled a plug, and it was heavily fouled and had carbon
tracking up the insulator. Replaced plugs, wires, and COP
boots thinking that was the problem. Nope- still has a light
misfire. 90% of the misfires are coming from cyl#6, with a
few randoms from 1,2,4, and 8. I swapped cyl #6 coil with
cyl #3, and cyl#6 still has a mis.
