My truck started running real rough every since i put my stall in and then it started cutting off everynow and then the engine light came on and it threw a (PO135 bank 1 sensor 1) and a (PO155 bank 2 sensor 1) so i went ahead and replaced the front 02 sensors and in the process i had the battery cable loose, so the battery was reconected after replacing both 02 sensors and the engine light was cleared but the truck still ran rough when i drove it and i knew it took a while for the computer to learn itself so i thought everything was fine, but then i drove it a couple miles down the road and the light came back on a now its showing the same two codes, so have any of you had this problem and what do i do now?

 

delete the O2s with a tune

 

cant delete the front ones, thats how the computer tells how much fuel to dump.. try and get the code cleared with a scanner..

 

but will getting the code cleared fix my truck running rough because its running pretty bad, like i said i already had it cleared once and it came back on again after i put the new front o2 sensors in

 

I dont think leaving the battery cable off really clears the codes but I could be wrong.. If the computer still thinks the 02s are bad even though they are good it will still cause it to run bad because the computer is trying to compensate for it..

 

i don't know either, but i did ended up going to the dealership this morning and they put some computer on it and they said my 02 sensor's some how got too hot and it blew the 02 sensor fuse in the fuse box under the hood but they said that they would have ended up clearing the code, which they could be lying but it ended up costing me $35 but the truck runs great now and im happy lol, but thanks for the help man!

 

hmm interesting.. glad you got it figured out..

 

yea me too, well i appreciate the help man!
