When you have BLM's that are widely split, how does the PCM decided which to believe?

 

it controls both banks separately. it can add/remove fuel from eash bank as needed. problem comes when it doesnt see a change and keeps adjusting for a false condition and the car starts running like crap. split blm's seem to be a common issue with cammed LT1's. Ask me how I know Sometimes my car runs fine, and sometimes the blms are whacked. I cant explain it, yet. Im leading towards a leaky injector though.

 

OK, thanks. Mine is doing the same thing, so I'm going to have to start looking for the problem.
