I took my car in to get a 2nd siren and battery put in, and when i got it back my CEL was on and all the setting on my vtec controller are retarded now, I had that s**t tuned and i dont know how to set it back to how it was, it says my pressure is -545 at idle is that bad? i dont think it was at that before i dropped the car off, i told the guys that work there and they said absolutely nothing they did could throw the CEL, im guessing the just disconnected the battery and it ruined my VAFC settings and in turn spazed out my ECU, when i got home i disconected the battery again (and my 2nd alarm went off wooo hoooo) and when i turned the car on again the CEL was gone, and hasn't come on since (7 starts) so i guess my questions are, what should the pressure read? and now that the CEL is off does it mean that if i got to smog it, it will be ok? someone help please thanks
