We replaced the idle air control valve last week with an OEM Mitsubishi Evo 9 idle air control valve and the car has been running great. I drove it home today and it was running good on the drive back.
Pros: car running great, good on drive
Vehicle:
Mitsubishi Lancer
I am running one of these from a crown victoria. The inspiration came from the fact that I have seen multiple crown victoria engine swaps to mustang newedges and even though people need to swap important and critical parts such as the oil pan, oil pickup tube, oil filter adapter, people tend to leave the idle air control in there from the crown vic and everything seems to work fine. The only difference I noticed was the the connector is oriented a different angle.
My car works fine as well.
Pros: works fine
Vehicle:
Ford Mustang
Bringing this back from the dead, because i found it in the "search", and i used one from the Hyundai i found in the junkyard, which seem more plentiful. Exact same part, and part number, and its from a 2001 car, instead of the 25 year old one that was in my car.
Pros: exact same part, plentiful
Vehicle:
Hyundai
it came today threw it in and tested it out everything runs fine, a lot better than before! it works!
Pros: everything runs fine, works
Vehicle:
Volkswagen Scirocco
When I bought it, I was made aware of an idle hunting issue - whenever I push in the clutch or return to neutral and the rpm drops, it drops drastically, almost to zero. It then bounces back up and will oscillate slightly before finding idle around 800-1000 rpm.
Cons: rpm drops drastically
Vehicle:
Volkswagen Jetta
I took the Bosch idle control valve off it and replaced it with the Dacia one it started instantly but with the same idling problem.
Pros: started instantly
Cons: same idling problem
Vehicle:
Volkswagen Golf
With my car I have two mechanic fix it. 1 1/2 years ago the first mechanic tried 3 different aftermarket idle air control valves (2 from Import Direct which is an O'Reilly in house brand and 1 different brand) to fix a low idle issue I was having and all 3 did not work. What finally worked was an OEM Mitsubishi idle air control valve shipped from Japan.
Pros: OEM valve worked
Cons: aftermarket valves failed
Vehicle:
Mitsubishi Lancer
