TPI IAC

Is it possible for idle to get stuck on high because the iac(pintle) is sticking or not coming back in quick enough??

Re: TPI IAC

check the throttle cable there are some washers behind the gas peddle that get hung-up sometimes. iac could get stuck if there is alot of carbon build up

Re: TPI IAC

Yes this is possible. They sell a Noid light/IAC motor Tester (rent from Checker, Schucks, or Kragen) $6.00/day! if you do get a new IAC motor, your gonna have to recalibrate the idle. see the tech article on TPS and IAC adj...
