Was driving the car the other day engine running as smooth as. Hit de restriction signs and down to third and gave her some beans and all of a sudden, a really bad misfiring occurred as power was going on. Initially no engine warning lights so drove her home at under 2k revs still as smooth as. Turned her off then when restarted Check Engine light came on.
So far, I've taken coil pack off and cleaned all the contacts up and checked resistances on primary and secondary side and all are spot on. I've tried to read codes on my OBD 2 but coming up as connection error after the device has done its initial entering of the system.
Any ideas what this may be? Although she's 22yrs old shes sub 100k miles and runs lovely.
