i can't seem to fix my idle and stalling problem

[david200095367]

ok i start my car in the morning and set the dec setting to 1% 2.2 and 3.2. the car runs fine and does not stall, but when i pull it out of gear and leave it in neutral the car idles very high around 950rpm's. but after i drive it some more and the car is fully warmed up and i come to a stop it just dies. it wont hold its idle. i keep changing the dec settings to find the correct ones but no luck. i did the write up method to set it to the correct dec settings. what can i do? i need help please this is sooo frustrating.

maybe its just an idle air control valve dirty or needs replace or maybe the mass-air flow is dirty or needs replacing.

How do i clean the iacv or fix it. also i have a z32 maf which is not dirty at all.

pour in some seafoam into the IACV hose and see if that helps. are you recirculated? if your recirculated your dec air settings should not be turned on. if you're REAALLY pissed off and cant take it anymore...you might want to consider going blow through maf set up.

im running open bov. i will try the seafoam thing. but last time i did seafoam thru the brakebooster it was hard cuz it would shut off a lot.
