Re: Engine revs up when starting
Tune air flow startup tables are not correct for your engine and need adjusted. Another possibility is you have a vacuum leak that the initial startup opens the iac then closes it to compensate for the added air from the vacuum leak to bring the rpm down to the commanded idle speed.
