Idle Troubleshooting

Glenn,

Thanks for not thinking I was trying to be a wise guy with the IAC passage.

TPS = 0.54 v at idle, hot. It's adjustable, but I don't know what the range of adjustment is, sorry. I never had to adjust mine, but the hold down screws are in slots and it looks like there is a useful bit of adjusting that can be done.

I bought a used MT-2500 off e-bay. I'd kill for a Tech1A. The real issue is finding all the software for all the different systems. Old technology & all for an antique car.
It doesn't exactly agree with my tach when I scan the car at hot idle. My tach down there appears to read low to me anyway. Also, my idle seems to fluctuate between 650 and 675 when I scan it, sometimes even as high a 700 and as low as 600. The TPS reports in at 0.54 v.
