HPT won't log maf
You don't need anything special to log MAF Hz or g/sec, these
are straight PIDs (on a standard OS anyway, dunno about the
speed-density-only ones).
Check the power to the MAF, ENG SEN fuse and the at-the-
connector (should be a +12V and a +5Vish).

I will check that today, thanks.
There is nothing in the calibration file that I turned off by addicent is there? I look at anything airflow related that seemed relavant and I havent touched anything in there in ahwile, it all seems fine. I did add a pin to the pcm last year to log thru the EGR, but the scanner has worked fine since the re pinning untill now. I am getting a code for insufficient maf frequency hmm. I'll make sure the maf is getting power.

The ENG SEN fuse was blown. I haven't hooked up the scanner yet but that had to be it. Thanks guys, I probably would have tore the wiring harness out or something before looking there.
