I'm stumped. I swapped my headers and put on new gaskets, but the idle problem is still there. Here is what C and C checked:
-smoke tested for vacuum leak
-fuel pressure regulator check
-MAP and MAF test
-O2 sensor check
-ECT and IAC tested
-Checked emmisions, ok when running, but very lean at idle, causing rough idle.
What next? fuel injector cleaner? try swapping to a stock air box?(don't know why this would be the problem, since I have been running 50k plus miles with the same intake). Get a retune? I tried switching maps, but no effect. Where do I go from here???
