Hi, Guys, i just done modified on my car, but i found idle sounds a bit problem.
First, when i start engine, the rpm is around 900-1000, but sometimes is quite hard to start engine.
so the problem now is, after runing the car, and it get warm, the rpm start goes up, and stay around 1000 - 1200 during idle, and have sound boh boh boh boh boh when 1200 rpm, when 1000 rpm, everythigns is normal vrommmm idle sounds. i found the MFD there turbo boost, when 1200 rpm and come sound boh boh boh at the same time, the turbo graph show it drop a lot and up a lot, not stable, when 1000 rpm, its stable. is it my turbo problem? is it because the turbo, so the idle sounds like tat? and rpm goes to tat high? i am just using 264 cam.
Can someone please help me? please~ i ask for checking, but the mechanic keep telling me that is mapping problem, not parts problem. untill know still cannot solve this problem, sad...
Regards
Eric
