Hi Guys,
Long story short but recently i've had this issue on the highway where i've gone to drop down to 4th gear to accelerate at around 3.5-4k rpm and when i WOT i'm hearing these "popping" sounds coming outta the exhaust, then the revs will keep climbing and then "pop-pop-pop" a few times as it revs? Sounds like a misfiring or something?? Seem to only happen under full boost, driving normally shifting at around 3,3.5k rpm seems ok..
Wonder if anyone has encountered this and whether they know what it might be...
I've got a tune by Rich at richtune and the last revision was to solve the boost creep issue that i was experiencing at the track... It ran fine for a while and only recently started to experience this...
I've also sent one datalog to Rich but on paper it seem ok...?
The car has got the step 2 colder plugs but they were put in about 20-30,000km ago.. Correctly gapped at that stage... Surely they won't need replacing just yet??
Maybe it's the gapping? Or the coilpacks? (Thought if it's busted surely i won't be driving lol) - I know i'm going to check my spark plugs once i get some time this weekend but just want to see what everyone thinks before i go pulling stuff lol..
Anyways, any suggestion appreciated...
For those interested, i've uploaded the same datalog i sent to Rich.
