First thing is a rough idle and sometimes shakes until truck finally shuts off. I have changed the ignition coils, regularly checked spark plug gaps and replaced, checked for vacuum leaks, but to no avail. I have even checked the resistance for the ignition coils, but they read good after replacing. The only thing I know for sure is that the cylinder 1 continues to have a misfire code. Any advice on what to check next would be very helpful thanks.
have the same problem?
