After auto VTPS installed car idles high
hrmm So I checked the adjustment screw and it's all the way in (or what ever the lowest setting was, checked for leaks, nothing as far as I can tell. Could the tps be faulty? I wired it according to Joe's write up. It's idling at about 2000 then goes down to 1200 after little blips in the throttle..
-Do I need to calibrate the Auto vtps in MT?
-Could my IAC settings in MT matter?
- Also the PO decided to shave the inside of the throttle body to remove the small hump per say on the inside.
- Which way does the vtps need to be facing (mine is plug out) and which way does it need to be adjusted??

ok so weather or not the tps is plugged in i get the same number for both at closed and WOT. it keeps changing though i'll try it one sec later and it'll go up by one point. then another sec one more point only after i close the calibrate tps tab..... now what??

+1 on wiring... I had the same thing.. I thought i did it right, but wasn't getting anything between closed and WOT.
I went back and triple checked my wiring. The way i actually did it was using banana plugs and alligator clips to create a temporary harness between the BMW TPS and the miata harness to make sure the wires were all correct.

well found out the throttle body was "trimmed/modified" to much allowing too much air to pass.... The PO is an idiot glad I got it for free!!!! Also I noticed on my MS wiring harness that I have some VTS wires, I wonder if that needed to be hooked up as after checking multiple time about the wiring it still didn't read a thing
