Re: Gap in AIC valve at rest? Posted by SWEDECAR [Email] ![]() ![]() ![]() In Reply to: Gap in AIC valve at rest?, NP ![]() |
You have the two wire AIC valve which has a spring loaded limp home function to it.
In rest position (no power/ground connected) it stays open a little bit.
Actually the opening you see is the back side of the valve.
If all the settings are not adjusted properly, the valve closes completly and thus exposing that small opening in the back allowing a higher base idle (limp home).
The LH 2.4 and up idle systems can be tricky to adjust properly and I can't really put it in print how to set it up.
If you pinch of the hose going between AIC valve and intake, the engine should be at about 4-500 RPM (not higher) and not much lower either with a cleaned out throttle body and no other vacuum leaks.
