Thread: here's one for the diesel experts!

hi all,
finally sorted the issues of the wild day at cityview & the associated damages & thought i was in the clear when a strange problem has reared it's head on me.
i drive a defender extreme td5 with a tunit chip piggybacked to the ecu.
if a drive around town there is a bit of vibration on acceleration, however what has me stuffed is that if i drive at 100kph or thereabouts for a while then cut down to 80-60 i get what feels like a really bad missing going on.
not being used to diesels i wasn't sure what to make of it.
i was coming back from the titans game last night to brissy & the missing kicked in at around gaven & continued until home.
any thoughts?
i am reckoning on either fouled injector or possible wastegate issue.
thanks in advance for your suggestions.

Check your injector harness for oil also. Mine was running on 4 cylinders when mine got gummed up. Cleaned it out and I went for a couple of months before I had to clean it again.
