So..... I got a new one for you URD users out there. Maybe one of you can help me out. Im still having issues with my AFR's, the AFR's fluxuate. Just cruising or even at idle they run between 13.5 - 15.9ish. When ever I would go into boost the AFR's didnt change even though I have the fuel/timing activated at 0.5 psi boost, except when floored. Then it would run extremly rich, like 9.0 - 10.0 AFR. This has been going on for a year and a half or so. Up until about a month ago, when I hit even 0.1 boost my AFR's get extremly lean (and even floored), like 20.0 AFR. Yet if I cruise in vacuum it still runs between 13.5 - 15.9 as stated above.
Im kinda stumpted and alway have been with this URD kit. Even had a tuner help play with it with no luck. Im kinda doubting the sensor on the LM1 is bad because it seems to be working fine while not going into boost. I still drive the truck around but dont go into boost what so ever. Thank god its flat every in AZ unless going though the mountains.
Im kinda thinking it could be either the FTC, Fuel Pump and or the Fuel Regulator. I have already change my spark plugs, pvc valvle, check valves and cleaned the mass air flow sensor including air filter. Also cleaned out the throttle body.
Any suggestions would be greatful.
Also to the other that know me, sorry I havent been around in quite a long time. Got a new job and dont get time to dink around anymore, even after work. Work, go home, sleep, rinse and repeat.
