Idle fixed

01 Nov 2017

$100	new air regulator
$10	air regulator connector & terminal kit

I finally tracked down the last of the idle problems with this car: the air regulator was bad. It would work fine when I first started the car and the idle would eventually drop to 800 RPM, but once the car started moving the air regulator would open back up. A new air regulator fixed the problem. All in all, here are all the things I did to finally get the car idling right:

replaced and reset the TPS
cleaned the IACV
replaced many rubber hoses with silicone
tested the EGR, AIV, and PRVR vacuum lines for leaks
replaced the air regulator
