just a question. i just hooked-up my vafc. and you know when you put in the initial info on it, and when you go to the sensor check ( like the pressure sensor, and the throttle sensor, etc). it was reading kinda low the one it was saying in the book. and the question is.... is it doing to cause any problem? and how wold you be abele to find out and fix the problem. BTW i took the vafc out cause i was just testing it, and it was doing that problem, if it was.
