Question

I have had the plugs, wires, ignition coil, and the 5th cylinder fuel injector replaced. I have had the cylinder checked for proper compression. I have used SeaFoam in the tank and on the valves.

What should be my next move?

Answer 1

Hi there,

The next step should be a leak down test on cylinder #5. Also, the wiring for the coil and the fuel injector should be checked. Either could contribute to the problem and cause it.
