It had a bit of a lean misfire after the cam, but still felt OK. I tried correcting that slightly with the adjustable MAF, but that just made it super rich.
Got that fixed somewhat last night while we were logging with the wideband on, but the readings were inconsistent and it felt really sluggish still.
I don't think it's the cam, or anything that can be corrected in the tune, yet.
Need to have the plugs/wires/O2 checked to start. It's almost like some plugs are now fouled and causing a different miss and/or the O2 is not giving good data. | | | |
