Aight this ones proving a little difficult for me and it's gonna be even harder to explain.
07 S-GT ej20 single turbo blah blah. The cars a good wee thing but sometimes I find it has a bit of a rough sort of 'skip' or hesitation. For example, down shift and decelerating the car and sort of jerk a little bit and same thing when applying more throttle. It's not very consistent though so some days it will do it, some days it won't. Idle fluctuates a little bit but it sits around the RPMs you'd expect when the engine is cold or at operating temps.
So far I have changed my spark plugs (were due anyway) and cleaned the MAF sensor.
One suspicion I have is my sort of bundy intake side (just half the airbox + filter) as pictured. Whether this could be a culprit I have noooo clue.
Other than this, the car seems to drive fine. Boosts fine, accelerates as it should.
I thought of cleaning the throttle body to see if that would make a difference. Anyone else have any ideas/experience with this kinda issue? The car is great but I feel like it could be running a bit better...
