182 misfire, progress?

[Joe Smart]

Just changed the spark plugs on my 182, they've been changed last year but wanted to see if anything stood out and it did.

Any suggestions on my next step?
This is cylinder 4 (belt end) with the black deposits

1&4 sooty so i'd be thinking coil pack.

The picture doesn't do the top one any favours, it's the same as the other 2

I'll get some tomorrow at work. I'm mixed between the coil pack or the injector.

This is the only code I've had.
Scanned the car a few times.

Injector... have it running with the misfire and fuel rail guard removed, unplug one injector at a time (not the injector itself, just the plug), it should run even worse until you get to the faulty one which will make no change to the running. Mine was injector 1 near the belt.

Done this but nothing stood out

looks like injector, surprised delphi didn't bring a code up but the plug is the give away :wink:

you can check resistance on them if you want.

I thought as much, someone else's opinion has settled it.
I'll get one fitted this afternoon

Was indeed the injector. Running like a dream now. Even sorted the rough idle.

did you clear codes when you changed the injector?

No, this is just after doing the injectors. Cleared and I'm going to scan it again I a week

kick it's head in for 30 miles or so and see what it brings up then.

Always an injector, weak point on the f4
