Fuel System Lean Bank 2
Fuel System Lean Bank 2 I put the car on the Tech2 and checked the DTC's and it sets a p0104, fuel system lean bank 2. It was setting a code for insufficient switching of the front o2's so I replaced them, and it doesn't set a code for them now. But it is setting this one. Think I have and injector on bank2 bad? What do yall think?
Re: Fuel System Lean Bank 2 "Sleepy" sensors put out low voltage that looks
like lean. Headers make O2s run colder, often too
cold to work well. The older they get, the slower
they get; the colder they get, the slower they
get. The slow switching code will probably be back
in a month or two.
I'm just guessing that anybody who has a cammed
stroker motor has long tubes....
You know what would be a cool (heh) thing for
LS1 headers? To have a little "gas tube" up at
the front of the primaries with an O2 sensor
bung, rather than making the sensor sit back in
the collector. It could just be a 3/4" cross-web
and not affect flow at all, but give the sensor
the nice hot gas it wants. Put the bungs between
#3 and #5, #4 and #6.

Re: Fuel System Lean Bank 2 I have the same problem with the TPIS Header, funny how the manufacture never heard of this. I would suspect that the O2 sensor is not calibrated for the conditions created by the headers, cam, which allow more air through the overlap. Too bad there is not an O2 sensor that would command a leaner condition and bring the Chamber Charge back to design AFR. I turned that anoying check engine light test off.
Re: Fuel System Lean Bank 2 If you have a TECH2 and think that you have a bad injector, why not do the injector pulse test with the TECH2? That should let you know if it is a bad injector or not.
Also, are you getting misfires on that bank?
