the past 3 days ive been having trouble with my car. out of nowhere, it wont start anymore.
i have tried many things like a brand new map sensor, checking the wiring, adjusting valves, ensuring timing is correct, cleaning IACV and throttle body, replacing throttle body gasket, confirming injectors, fuel pump, fuel supply, and spark to name only a few.
i have nothing else i can try from my personal knowledge. im hoping somebody here can check my datalog and calibration and help me fix this problem. im stumped!
- key points ive noticed in this datalog: AFR is either 10.7 or 14.7 with nothing inbetween. im not sure how these widebands read but my other external widebands would lean out after a few minutes and continue measuring oxygen content as long as it could
- MAP is -23 to -29, how can this be? im at 3,200ft elevation. typically never see below -3 here for atmospheric pressure with key on and engine off.
