Working on a 2001GT,

Has a miss in #5. (was intermittent, now almost constant). Also occaisional missing under load.

New plugs (and fuel filter). Cleaned the holes the the plugs go into. Have swapped coils, have swapped injectors. Next is to check for voltage at each. I will get a noid light to check for voltage at the injector. How do I check voltage at the coil?


Also going to check compression.

Any input is appreciated

What plugs did you use? Check the red wire at the coil, that is the 12v. The other colored wire is the RPM signal.
