Iac Housing ?
Have been having high idle problems with a 88 5.7 tpi camaro. Bought new iac and housing from tpis. Installed and now idles even higher. Question is in putting on the new housing it only uses 3 bolts, could air be pulled from some of the open holes in the bottom of the tb? tried to set minimum air as per everyone here w/ no luck. Cant get idle in drive to fall under 900 rpm. any advice would be great as i am willing to try anything i havent already tried. Thanks, Jason

Re: Iac Housing ?
Does your IAC have an adjustable pintle? as per the manual, my 90 305 tbi has IAC legnth requirement of less than 1 and 1/8'' from flat edge to tip...

Ya read all abt setting length did that and still no luck so i took it back out put it in a bag and connected it nothing happened. returned the cheap part bought the more expensive one and presto she is purring like a kitten. bought a bad part, not the first time this has happened hopefully its the last. Thanks for the advice.
