high idle
Hi guys need some input.
Just did head/cam/intake and ported/polished throttle body, dyno tuned etc the problrem is i can go for a drive and it will run perfect I can go for the same run about 70 miles and the idle when you pull up is running at about 2000 rpm after about 8 seconds it will drop back to the set idle of 850rpm, while you are driving at say 50 mph its like being on cruise control.
Any ideas

It could be either a problem in the tune or it could be a vacuum leak.
More than likely you have a problem with the tune. Too much "running air flow" in the idle table or timing map that hasn't been properly smoothed. Are you able to post up a copy of your tune?
