Thanks, it'll be a couple days...

Thanks Aksl

Fast355, sorry for the confusion, it idles at 1300 and won't go below. I've changed the TB with a used one, a new PCV valve, sprayed contact cleaner all over, nothing. My son checked...

Fast355 - I see you have tuned Nissan/Infiniti OBD2, have you ever messed with a 2002 Q45 4.5L V8? Mine won't idle under 1300RPM any more. I don't want to step on this thread, maybe I should start...
