Hello all,
Lest week my FR-S w/ unichip (also AFE CAI & DC cat-back) started stalling at red lights. CEL comes on, read code p0102 (MAF low voltage). Cleared, went fine for a little while. Stalled again at another light. Didn't clear code. Then, it starts misfiring/stuttering during acceleration. No flashing CEL, but enough to feel. After, car would not accelerate past 50% throttle. I could push the pedal down fine, but would not accelerate any harder than at 50% throttle. I unhooked Unichip, everything is fine. Any ideas? I hate to have this $450 chip sitting there doing nothing.... but I'd rather have a drivable car...
Any input is appreciated.
