2002 Chevy Blazer Electrical issue
I got a P 300 random misfire code from my 2002 chevy blazer, so I changed the spark plugs, spark plug wires, ignition rotor and distributor cap. After driving the truck awhile I got a new code. P 304 Cylinder 4 misfire. Tried replacing the sparkplug and the spark plug wire and still no difference. Not sure what to try next... Anyone got any ideas?
