    Intermittent Asr

    After i installed a head/cam/lt combo, my ASR is intermittent. I would assume this is due to the cam. Its pretty big, and there is not enough vacuum. The ASR goes to normal during driving, but comes on and off when idleing. Also my CPU is throwing a Rearend sensor code. Has anyone had this issue.. Is there a way to tell which sensor is in trouble, or is this probably wiring or vacuum.. All input greatly appreciated.. KD

    Sadly now demodded :(

    If the rearend code your speaking of is the "Lowtrac" light coming on then it's probably also related to the cam you installed as it's probably not pulling enough vacuum for the power brakes. That light also comes on when the ABS has to readjust.

    Did you retune the PCM after the install?

    As far as the ASR is concerned I'd just turn itoff.

    No its not the lowtrac light, the computer says its a wheel sensor on the rearend. THe ASR light comes on and off, like im actually flipping the switch.The PCM has been tuned 2x with HP tuners. I guess i just need to go ahead and turn the ASR off..

    i would agree with 67camarorsss.
    the ABS idea. if its a wheel sensor that the code is pointing to, it could be the abs sensor. as for why it would happen... no idea.

    Thanks

    Alright,, I guess i will pull them both out and see if i pulled on the wiring or something during the head/cam install, or maybe its got some metal shaving on it from the exhaust..
