Rich a/f while cruising?
The last few weeks my car has been running around 13.3 to 13.6 a/f while cruising and will jump back to the 14.7 area once in a while also. Then when I go wot the a/f stays roughly the same, you can feel the car is getting no fuel so I know it's not the wideband o2 sensor. I don't have access to a scan tool locally so I replaced some of the basic things. I swapped out my injectors with a set of rc 650's I have and replaced all injector o-rings, intake mani gasket, throttle body gasket, exhaust mani to o2 housing gasket, and o2 to downpipe gasket. Replaced the up stream and downstream o2 sensors. I bought a set of new 4306's and just bought some new msd wires 3 months ago. I boost leak tested the car swapped out the tps sensor with a friends and still the same issue. The car idles perfect with no hesitations or anything. So I'm assuming either map sensor or iac. Does any one else have any input or ideas?
