Great thanks Guy's Ill give that a go. I've only got a cheap scanner (ebay) brought it for my first wh (hemi) Had a Bad O2 Sensor. Seemed to work ok on Our kj 2.8crd, That will be why it didn't give me much info when I scanned it lol.
Ok Off to jeep In a few Days and get it scanned.

Thanks again for all your help so far

just putting this out there, there seems to be a lot of soot in the exhaust my commander was clean from the dpf on, i installed a cat back exhaust with high flow muffler and dpf, now ever since putting it in it's a little hard to start and it blows a big puff of smoke

I generally found
Black smoke over fuelled
White smoke under aired.

Is it smoke or steam?

Hey Guys,
Just an Update, Thanks for all your help you were right on the money. I didn't bother getting it scanned because I tested the resistance on the first two glow plugs on the passenger side (easiest to get to) and they were f###ed, I had to set my Multi meter to 2m Ohms to get a reading on one of them.
So I just went out and brought 6 new glow plugs. The first start after changing them still smoked however every start after that has been good.

Thanks a lot for your help once again now I just need to do the CV on my front prop shaft (not sure if its diff side or T-Case side) Its not making a very nice noise ATM lol
