My glow plug fault for cylinder 4 turned on about a year ago. I finally got around to replacing the harness as it was cracked and not very nice looking.

I got it all done, started the car up and the CEL came back on. So I reset it, restarted the car and it came back on. I double checked that the harness was snapped onto each glow plug, there was a definite snap feeling/sound for each of the glow plugs. I did use silicon grease on the connector so I think that is good to go.

Does this mean I need to replace the glow plugs?

Suggestions?

thanks,
david

I checked the impedance of the glow plug and it is open. The others read ~1ohm.

Is it OK to replace just one or should I replace them all?

thanks,
