Today was truck day. The problem was indeed the carpet padding. It had not one but two layers of 1/2” padding. Took it all out, and the had to tighten the cable about an inch. And now, it moves up and back like it should. Thanks guys!!’ IMG_1388.mov

The carpet is aftermarket with a pad. I hate to take it apart again, but I will and I’ll let you know. I didn’t even think about the spacing being that tight. Thanks! Joseph

It won’t slide because the middle sinks into the carpet.

This is how it happened: I wanted to change from bucket seats to a bench, so after searching for several weeks, I found an excellent specimen at a small salvage yard. I loaded it up and took it to the upholstery shop. About 4 days later, it was ready and really nice. I took it home and removed the long console and the bucket seats, put the bench in and it looked perfect. Sat down and felt amazing like a brand new seat. Then I tried to move it forward and it would not slide. That is when I realized that the junker it came from was not a 4x4. I tried putting spacers under the seat but my head almost hit the roof and it still wouldn’t slide back and forth. Has this happened to anyone else? If so were you able to make any modifications so it would work?

Ok, I’ll give it a try and let you know. Thumbs crossed. ( did clean the throttle body, but I used some carburetor cleaner I had. I hope I didn’t mess it up.)

If you mean .54 volts, the truck runs pretty good except that when you first start it , it dies. Restart and it runs good. Sometimes when I let up on the gas, it will die.

I don’t understand what you mean by 54%, At 4.33 volts input voltage x 17%= .7361 volts. This is the reading I should be getting. I am only able to get 0.54 volts output. .54/.7361 = 73.61% of where it should be.

Yes, I cleaned all grounds and pulled ever connection I could find. I am using the information in your Tip number 8 to adjust the TPS. I’m just trying to understand why the original throttle position sensor can be adjusted from 0 to .55 but no further. And why the new ones will only go from 0 to .17 Also the low input voltage must indicate something?

It’s definitely on the correct side.

I I went thru the steps to adjust the TPS on my 88 Comanche Chief 4.0. My input voltage is not 5.0 volts, it is only 4.33. So using the ratio, the output should 0.736 volts. My TPS will only adjust to 0.54volts. I bought two different ones, one from O’Reilly and another from Advance Auto Parts. Both only adjusted to 0.17 volts. I put the original back in. The question is: is the low input causing the TPS to not be able to adjust or if the input voltage really doesn’t matter as long as the ratio is correct, then can anyone recommend a new TPS that will work?
