I've trawled through the various links and discussions and hoping you guys can clarify something for me please:
1. Does this issue affect the MN 2.5 engine? I'm having issues and the Mitsubishi tech on the Gold Coast is trying to tell me it doesn't. Wasn't sure if the redesigns had negated the issue on this model.
2. What do you actually experience with a "surge". Mine is more of a miss / stutter. Same thing?
Thanks in advance.
Hi Jappi, I was having "miss/stutter" problems with my 2010 MN Ute. Shortly after setting off on a cold motor it would miss/stutter once or twice as I was driving along, typically on a light throttle position. (a.k.a. the Fun-GO-Pedal
) The symptoms disappeared though once the donk warmed up. Anyway, I read another post about similar issues being caused by a dirty MAF sensor so bought myself a spray can of "CRC MAF Cleaner" for $25 from SoupyCheep and gave mine a good squirt of it and as if by magic, all of my cold donk's 'miss/stutter' problems disappeared as if 'in a puff of smoke and fairy dust'
Anyway, it might be worth a try for you too. Even if it doesn't prove to be the exact cause of your own issue this time, the can of MAF Cleaner wont go to waste because it's 'good maintenance practice' to give your MAF sensor a spray clean every time you replace the air filter anyway.
PS: Just don't smoke while using the MAF spray or inhale the stuff either unless you've got a death wish.
PPS: Your Gold Coast Mitsui tech is tellin you sweet little 'porkie pies' because the MN 2.5 donks are still affected by exactly the same EGR induced carbon build up problems. It's just that with the re-positioned MAP sensor port on their later version re-designed inlet manifolds they are not as prone, to oily carbon 'gunga' (that's a technical term
) build up, clogging/blocking their MAP ports, and hence, suffering from consequential 'limp modes' as a result of those blocked ports, as the earlier Triton models were, before Mitsui re-designed their inlet manifolds. I would strongly suggest that you have another -close look- at Koshari's post, directly before your own, above, if you want to do something 'effective' about stopping the EGR induced carbon build up from occuring in your own MN 2.5 engine.
