Once you see the bottom of the switch it will be obvious what’s wrong. It’s just a cam with two lobes 90 degrees apart, one for the off-idle and one for the full throttle.
I have no experience with GW’s switch, since mine was fine after I set it, and the PO had really messed up the adjustment. Since they warrant their stuff, I’d go for it if you need one. I’d also replace the TB sealing ring while you are at it. Mine was completely compressed and hard as a rock, making it a potential vacuum leak.

Thanks Stuart,
I would not describe the switch to be 'immediate' upon applying throttle, there is a small distance the cable retracts before it engages. The adjustment bottoms out and will not allow me to make it any closer. Also, the switch does not switch at full throttle, however the van seems to run great even at full throttle.
Sounds like I need to remove the TB and inspect/clean it. Any thoughts on Gowesty's vacuum operated TPS? Worth the money?

Use a voltmeter set on ohms to check, and the TPS should switch immediate upon moving the throttle, and switch again only at max throttle. |
