Help with idle over boost problem.
The other day i was in my car letting it idle for awhile when i heard a low grinding sound coming from under the passenger side dashboard. It then showed on the PFC that the car was boosting at 1000rpms (about 0 to 3.8) and the A/F ratio was super rich (10-11). The brake pedel pressure seems to fluctuate when rpms are higher and the emergency brake is useless now.
Does anybody know what this problem might be? Bad PFC? Bad Wastegate? Just wondering what i should look for before i start taking the engine apart, because it could be something simple i just didnt think to look for....
thanks
btw this is on a single turbo setup, with all basic mods, fmic, rad, etc..
