fuel problem

Post by muddyjunior »

Hi,
I was wondering if any one has had this problem. I have just changed the fuel filter on my Diesel 4.2 GQ patrol. When I went to restart the blessed thing it was surging as if not enough fuel. It would run at 1200 revs for say 3 minutes and then drop down to 600 revs for a few minutes and back upto 1200 again. If I didnt hold it at around 1200 revs then when it dropped in revs it would stall.
After a while it seemed to come good, I thought maybe some air in the system but now when you rev it a little bit and then let it idle, it runs very rough as if there is not enough fuel.

Any clues would be greatly appreciated.

It wasn't fully bled, just pump the bleeder/primer more.
