    Warm idle IAC is 16%. I assume I need to open the throttle a bit and do a TPS Autoset.

    Yes, a TPS Autoset is required anytime you adjust the idle speed screw.

    Half turn of the throttle blade screw and I’m down to IAC of 10%. I’ll make another adjustment to get down to 5% range recommended.

    I also adjusted the IAC Ramp Down RPM up to 1000 and the IAC Hold down to 20%. Overall improved tendency to stall when rolling to a stop, but it still happens if the RPM is low when engaging the clutch.

    Finally, the cold start still requires a bit more cranking than I think should be necessary and the hot restart requires minor throttle input to fire. Should increase the IAC Parked Position?

    Also, noticed my fuel pressure is now reading out of range. Using the Holley SS 100 psi sensor; which has all of about three hours drive time on it. Was indicating 39 psi during previous drive. Now thinks there is 112 psi of fuel pressure. Any ideas?

    Is the sensor mounted on the engine? I've had the Holley sensors fail very quickly if they're mounted on the engine. I finally built a remote manifold for the firewall and then ran #3 line from the engine to the remote manifold, so the sensors were not engine mounted.

    The FP sensor is currently teed in with my Auto Meter fuel pressure transducer, which is behind the passenger shock tower. My oil pressure sensor is mounted where the OEM transducer was originally, beside the oil filter. No issues with this one so far. Both only have a couple hours of use.

    If you think you have a defective Holley pressure transducer, contact Holley Tech Service (LINK).
