I have just installed a cam and i ran auto tap and it is telling me that all 8 cyl are misfiring. Is this normal. Also can A-tap tell you your iac (idle air control) Count, If so were.
Thanks for your help.
Hi there,
I would say that maybe your crankshaft relearn was not done. Camshafts will give a different reading for misfire diagnosis, so this may be your issue.
I would do a relearn first, then proceed with diagnosis.
Besttoyou, c4c5
