OK, so as some of you know, I had a wonderful escapade with one of those granatelli MAF sensors, long story short, I hocked it in frustration and went with a 5 pin Delphi with screen/fin intact etc. Definitely helped correct some of the surging issue. I also replaced my O2's with two Bosch pn#15703. Now it seems no matter how I alter any systems I'm getting a consistent BLM of 108 on both sides. For reference, before I swapped the MAF's, with the granatelli I was getting about 138-145 BLM's. If anything, I'm starving my motor of fuel, definitely not running rich. I did find a post by mr Injuneer in here somewhere, checked everything, flow rates appropriately calibrated for the change in fuel pressure, good working fuel pressure regulator (no damaged diaphragm) O2 harness(es) are not suspect as the BLMS weren't split with the other sensor.
It IS possible that these injectors might be leaking; they're old, beaten on and probably have pintle seat wear. They do not exhibit any visible form of leaking though... I originally thought the low BLMs were due to my timing advance at any given rpm or kpascal, but every timing combination I had time to do had zero effect.
Ideas? I have been reading about this wherever information is given, checked all the possible causes I could think of.
