CEL cherry poped w/codes...
was wondering if i could get some help from a different bunch... Im on Audiforums mostly... Heres what i posted there:
17964 - Charge Pressure Control: Negative Deviation
P1556 - 35-10 - - - Intermittent
16502 - Engine Coolant Temp. Sensor (G62): Signal too High
P0118 - 35-10 - - - Intermittent
17536 - Fuel Trim: Bank 1 (Mult): System too Lean
P1128 - 35-00 - -
I have gotten the 17964 code several times after getting chipped. I guess its from overboosting, and had this code before putting in the n75 j valve in. It goes into limp mode and i get this code.. all ive ever had to do was restart and limp mode went away even if i didnt clear the code. NOW... i cleared the same 17964 code last night and its back, and i have these 2 other codes along with a cel and stuck in limp mode-max 10 psi. If the engine coolant temp sensor is bad, wouldnt that cause me to run rich rather than lean? and i posted yesterday about the "cracking noise" i heard at wot like endle had about a week ago too.. Im thinking it was in fact detonation due to running lean. I've dreaded this day for almost a year now. i feel so violated.. please help me out with some ideas if you got em! Thanks.

Pinched N75 hose, or bad N75? Stay away from the crackling or boom.
Check all of those vac lines and maybe see if the stock N75 does the same thing. How much boost are you running at peak?
