Just changed plugs and wires on the Jeep. Replaced OE wires with 8mm Taylor silicone wires and OE Champion spark plugs with NGK. The old plugs had a 0.060" gap.
Now I have p0300 code, random misfire with an obvious miss and unburnt fuel out the pipe. I've checked resistance in both components and everything checks good. I added more split loom to prevent inductive pickup as the wires run behind the valve cover.
My question is: could lowering the resistance of the circuit cause this code? I've cleared the code several times to no avail. Any tips would really be appreciated, thanks
have the same problem?
