not wanting to sound rude but what could be wrong with the afm? i did took the thing off and gave it a quick cleaned, and from inspection,i thought the thing doesn't have too much mechanical components nor electrical components for it to be related to any problem.
as for the intercooler, while carbie cleaning the throttle body, i did took some of the IC pipes off to clean off some of the oil, i remember i did tighting up all the clamps but will pull it apart and pull it back together again tomorrow.
uummm at this point i gonna say no to a new comp wallet is quiet empty now after easter.
by any chance could be related to the crank sensor?, cos i got it replace a few days before this rev problem
This happen a day after i degreaser the engine, but i did took the car out after i cleaned it, and it was fine
