Is a vacuum hose supposed to go here? What would it attach to? (Page 3/3) Patrick OCT 17, 05:57 PM quote Originally posted by stapler8: I adjusted the Throttle Position Sensor when I installed it. I know you're new at this, so I need to ask... How did you adjust it? stapler8 OCT 17, 06:03 PM When the bolts were a bit loose during installation I rotated it to the most "closed" position on the butterfly, that seemed like it would make the most sense to me unless of course that would cause it to stall. Ended up with a 1200 RPM idle on average.

No.... you can't just be guessing with this stuff. There are 20 years worth of posts here... including how to properly set up a TPS. The general consensus is that half a volt at idle is good. This video is for a 2.8, but the gist of it basically applies to the 2.5 as well. stapler8 OCT 17, 06:41 PM I only started actually using this forum very recently, didn't realise it was so active. I'll do some research tonight and reinstall it tomorrow morning then report back. Thanks for letting me know.
