    It will idle up to 2000-2500 rpms without dropping until it's put in gear at which it idles around 1300-1500 which still seems a bit high.

    yea something is wrong.

    if you put your stock pcm back in does it still does it?

    the idle should be 1000 at start up then go down to 800ish

    I have been sick and haven't gotten the chance to swap them out again. I plan on doing this later tonight tho. Also i have a 3.4" pulley I'm putting on as soon as I fix this problem. I currently have a k and n cai, zzp 3" down pipe with u bend delete and high flow cat, a 180* thermostat. I want to get colder plugs as well but stay with iridium what would you recommend? Will these mods be enough to keep away kr?
