It would be awesome if someone had some spare internal parts for these TPS's.
My old one's internal microswitch failed. I would get hesitation and it would buck when off throttle.
New TPS's are $$$$

They contain a couple of dollars worth of parts. It's been on my list for years to recreate a cheaper version....

Please please do

I'll bump it up the list, as soon as the digital timing belt tool is done....

By chance, did you adjust your idle after fixing the leaks? If your idle bypass is too closed it could be choking the engine. I would close it fully and count the 1/2 or full turns as I close it. Then open it to 1/2 or a full turn more than it was. See if that improves, if still rough, keep turning open small amounts.

My engine loves air so much, mine is fully closed and it's idling high LOL, but I am able to disable my idle stabilizer and the car barely runs, opening the air bypass smooths it out.

haven’t adjusted the idle at all since it was fine before this started. I did try inspect the TPS and found that the click was not there even after I adjusted the stop. I took the TPS out and sent it to the link above for repair. He notified me that the TPS checked out within tolerance so he’s sending it back no charge.

Once it get it back I’ll follow some steps I found on your post

How do I manually close the ISV? I’ve seen the test on TOMS video but that’s with the isv out of the car

From what I'm coming to learn, you cant "close" the ISV, but you can unplug it(remain static) and cap off the inlet. Effectively deactivating it.

Interesting findings with your TPS, did you try adjusting it before sending it off? There isnt much adjustment before it looses the click.

I'd put it all back together and try adjusting your idle using the Clarks Garage approach. I would be curious to know what your idle bypass is set to now, and if adjusting it works- where it ends up.

Yes I tried adjusting till I would hear the stop but I didn’t get one. Even when I pulled it off it wasn’t clicking. This concerns me since he said everything reads out normal.

If I can help, let me know. I should have a spare TPS somewhere...

Even with a good TPS the DME/KLR may not be receiving the proper signals due to bad wiring. The TPS connector is a good place to examine (under rubber boot).

With a multimeter you can check TPS signals at the DME & KLR.
