I just noticed that Franke - that the momentary Open Loop, while it's been in CL for several minutes, DOES CO-incide with the excession of 1.6 % TO.

I'll see if I can replicate that, and get exact data for it...

Default Re: 1990 Throttle hesistation

Why is the TPS% 1.6 at idle? .61v is high for idle.

It's not idling Dom.

Idle Voltage motor off, Ig ON, TPS is TUNED to 0.54V. Ig ON, motor on, it stays @ .54V.

I'm using a box wrench to bump throttle stop screw, 1/6th turn of the Hex bolt at a time.

And I was doing it SLOWLY, to allow parameters to '0' for that TO %.

TPS voltage, and TO %, in DM, are in pretty tight sync, and are posted in this thread a few pages back.
