IDLE ISSUE

[da240]

Well im like all the others here with idle issues. The car idled okay, there were a few issues so i decided to clean the IACV. Clean it in and out, bolted it back up and now it idles like complete ****. Idles between 600-1000 and as rough as can be, like its running on 3 cylinders or has some crazy cams in it. Once i rev it a little (over 2000) its fine but at idle it is complete crap.

PS. Also i found a weird liquid in the bottom of my intake manifold, kinda like a mix of oil and gas, could it be an intake manifold gasket?

check for gasket leak/vacuum leak. sometimes when it idles like that, there is air in your coolant or you don't have enough coolant. try bleeding the cooling system.

did u ever fix this issue? i'm having the same symptoms, pulled iacv on my sr20det and found black oil/gas on the gasket too.
