Come on now Beer 30.It took you 6 months to figue you had a bad IAC.Who you trying to kid?
AHHH Just ****in with you. :rollside:
Like i said before turbs have been out for probablly 60 hrs.When i went through my engine there were no signs of reversion.But it only takes a minute to pull a couple of plugs to double check after an idle through Thompson bay.
