ok so i thought fuel pump died when my car died on the road the other day but i filled the tank a lil more and got it to start it ran fine for awhile.....first time it died afr was 18 lean as shyt now that it starts again afr is at 10.5 and ltft's are at 25.9.....ive never seen that number before haha wtf is going on with my car bad fpr? car chugs and rough idles and if i give it gas it hardly goes.....im lost.....ii recently had to put in a fuel rail out of a jyard so im leaning toward fpr......insight anyone?

have you been that low on fuel before?

when was the last time you replaced the fuel filter?

[BoostJunki3]

yesterday and ive changed it 3 times since my e85 conversion

You sure your tank is sealed up correctly? when mine wasnt the ltfts were all over the place.

[BoostJunki3]

found the prob its the 02 sensor.....millis never leave 450 so its a bad sensor but the welder who welded the triangle shut on my pacesetters managed to weld the o2 sensor to the bung as well now what do i do this is a never ending string of BS

[KeithGTP03]

Welded the o2 sensor to the bung? Do you have a tuner? If so, cant you delete that sensor?

[BoostJunki3]

no its the upper o2 which the engine uses for fueling which would explain my afr issue........now i just gotta find out how to get this out or just buy some speed daddys and a new o2,,,,,

a torch. and alot of paitience you might get it out...if it's actually welded onto the bung......ick

[BoostJunki3]

got it out and replaced it still nothing.....now i noticed my exhaust being VERY moist and the car is running hella rich hope i dont have a blown head gasket time to check the oil......
