ever since i swapped my 3sge in my sixth gen, the idle seems to drop below 900, there's times where the idle rises how its suppose to but then it drops again. i was wondering if any of you guys runing swaps have encounter this problem? could b my idle valve or is it controlled by the ecu?

QUOTE (99gt3sge @ Apr 17, 2012 - 1:33 PM)  yes it conected, the hoses go to the plenum. Im not sure about the 3sgte but both the 7afe and the 5sfe have an 'AC Idle Up Control Valve'. It is located on the end of the intake manifold on the passenger side. I suppose the principle is exactly the same with boost as with n/a, you are just letting a small amount of air into the intake to compensate for the power used by the compressor. Mine went out and would sometimes stay open so that my idle would be way to high with the compressor off and then sometimes it wouldnt open at all and the idle would drop and get real rough with the compressor on. Replaced the valve and it fixed the problem. Though I had to get the valve at a salvage yard because there is not even a search term for idle up control valve at the autoparts stores. The dealership should be able to locate one though. |
