The next thing to check is going to be fuel/air delivery. Test the fuel injector for cylinder 6 using an Ohms meter. Unplug the injector, and take a resistance reading at the two blades on the injector. If the ohms reading is not 11.8 - 12.6 ohms, suspect faulty injector. If the injector checks out good, next do a check for intake air leaks. Using carb cleaner, sparingly and carefully spray the base of the intake around cylinder 6. If the skipping eases, suspect a faulty intake manifold gasket. If this checks, the next thing to do is run a compression test.

what do i set the meter on the check the reading??? do i check it with the car running or shut off??
Chevy Mechanic: Ron Z., - Chevy Tech - replied 8 years ago

 

You can usually buy a "multi-meter" just about anywhere. They are pretty common. When doing the Ohms test, the engine should be off. When doing the intake manifold check, the engine should be running.
