CEL on

[agent007]

i have reset the CEL by disconnecting the battery and also by clearing the codes witht the code reader machine. i keep getting codes P0171 bank 1 too lean, P0174 bank 2 too lean, and i think P1130 A/F Sensor- Bank 1 Sensor 1 and P0150 A/F Sensor- Bank 2 Sensor 1. but the thing is that i replaced both a/f sensors in march or april so there should not be anyway that they are bad. i know that the first pair of codes are do to the second pair. has anyone had any problem with this or know the solution? thanks.

you might connected the sensor in correctly. was it a universal unit or plug and play unit?

or maybe

your fuel just running lean. how many miles do you have and what modification do you have?

the sensor were factory so they just unscrewed and plugged in. but i do have a lot of miles like 110k. i have (think top speed) intake and greddy exhaust.

this problem plauged me forever. I replaced everything, plugs, coil packs, spark plugs, oxygen sensors, mass air sensor... and ya know what.. it turned out to be a fackin vaccum line that was off on the intake.

i swear i checked that, but the local place i took it to found it right away. Been fixed ever since
