Car has a 3 liter v6 and cylinders 1, 3, and 4 are misfiring. Codes are p0351, p0353, and p0354. I've checked the voltage repaired the wiring to the (COP) which all now have 12 volts, but all 3 cylinders still misfire. Vehicle has a new PCM was installed before I acquired the vehicle. I've also swapped out each of the (COPs) on all 3 cylinders with other (COPs) and its still misfiring. Im out of options and scratching my head. Can anyone advise something new to try?
have the same problem?
