ok this started yesterday. out of the blue i crank my car and start driving and my air fuel gauge is sitting lean basically off no matter how hard i press in the gas, and the car has the weird part throttle stutter hesitation deal, but its still smooth when im accelerating but it does feel a tad different. my friend had someone like this on and off in his hatch. this did it for like 30 minutes of constant driving and then all of the sudden it cleared up while i was driving and the air fuel gauge started reading normal bouncing around and staying near rich when i would WOT it. now it started doing it again out of the blue tonight when i cranked it after it sat for several hours. wtf? is it possible to foul out an o2 sensor or something.
my setup is sc61, 450cc inj, fields sfc hack, 9 psi.

 

any ecu codes? what kind of gauge are you looking at to get the reading? i hope you have a wideband

haha doubtful...

 

no i dont have a wideband and i dont rely on the gauge for tuning but i do look at it only at WOT when it actually does help a lot. and its telling something wierd is going on isnt it so its good enough for me for the next couple of months, the guage wouldnt cause this random part throttle hesitation, its not going bad, its just pickin up the problem, then all the sudden while driving the problem will go away no hesitation and not come back at all and the gauge starts bouncing all around and reading rich when i stomp on it just like normal. tuning has nothing to do with this random ****, it was fine all day TODAY. its something else, im thinking wiring, ill check it tonight i guess. no CEL codes
