Hi Guys, so as the title reads, I'm having an engine surge/hunting issue. Now it is nothing too major but obviously I'd like to nip it in the bud and ideas are always appreciated.
Here's the details.
2012 2.5ltr
55,000k's (yeah I drive far to work)
at 50,000 did the fuel, air and oil filter.
No obvious signs of leaks.
EGR is blocked (has been for a long time)
Here's the problem.
The engine seems to hunt in a rhythmic sense for +/- 100rpm when the engine is NOT loaded up. I should mention that its not abrupt or violent but just not smooth. It does this when the revs are around or slightly under 2000 and mostly so in second and third, but it might be in every gear. Like when you are sort of coasting at say 40Kph in second
seems to only happen when warm.
Tonight I will put a full tank of diesel in with some Morey's diesel smoke killer. I will also run the OBD scanner and see if anything comes up.
All other help and ideas appreciated, and obviosuly I am starting with the cheap and easy 'solutions' first
P.S... Please don't scare the shit out of me with fuel pump horror stories
