He is talking about new parts being DOA.Huh?
Well y’all, I’m defeated.
MAF connected runs with slight mis-fires counts on random cylinders. With out DashCommand I couldnt tell. Once she gets up to about 60mph backfires (kinda warm weather) previously cold weather no issues. No codes.
When I unplug the MAF and she toggles to to Speed Density purrs like a kitten. Driving all speeds, no mis-fires. So until I can get my hands on a OEM MAF from another solid running truck just to ease my curiosity I’m going to run no MAF. Check my plugs later to see wear. But she drives great. It needs the MAF to start, so I guess she is getting a kill switch, I already have the stuff.
How are your upshifts? My experience with my 1999 5.7 is that they are hard when the MAF sensor is off-line. If yours are acceptable then I think you can take that as a sign of a functioning MAF sensor. If not, then the converse.Re MAF sensor. When I had mine non-functioning (missing fuse) the upshifts were hard. Apparently, the PCM reads from the MAF sensor to set line pressure in the trans. No signal and it resorts to maximum line pressure hence hard upshifts.
The quality of your upshifts may shed light on how well your MAF sensor is functioning.
The app as awesome as it is, does not graph.
