RacerJJ Posted April 19, 2008 Report Share Posted April 19, 2008 I scanned my code that I got last weekend and discovered that it was fuel trim lean bank 2. I am sorry, but I don't remember the number and I cleared it already. Any ideas as to what this is? Has another o2 sensor gone bad and if so, can I replace them with wide bands in both sides? I only have the front sensors on both sides. The rears were removed when the cats came off. TIA... Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted April 19, 2008 Report Share Posted April 19, 2008 yes it sounds as if your passenger side front 02 is bad...I take it you threw a P0174? Quote Link to comment Share on other sites More sharing options...
Rausche Posted April 19, 2008 Report Share Posted April 19, 2008 If you wanted to, yes, you could have WB02s in both sides. Normally I would say it's a little OD, unless used in a well built truck, but since you're drag truck only... You'd be using them to simulate the NB02s, right?

RacerJJ Posted April 19, 2008 Author Report Share Posted April 19, 2008 Would it be better to just stick the wide band in the passenger side and get a stock one for the passenger? Quote Link to comment Share on other sites More sharing options...

AFAIK, the number 7 cylinder (driver's side, closest to firewall) has a habit of going lean in our trucks... If I had to pick a side to watch with the WB02, it would be the driver's side because of that... Quote Link to comment Share on other sites More sharing options...
