TurboedMJ Posted August 3, 2023 Share Posted August 3, 2023 What brand of throttle position sensor should I buy? There are many different options that all fit, ranging from $20 to $180. Can somebody give me a link as to what to buy? 1989 4.0 manual. Link to comment Share on other sites More sharing options...
Pete M Posted August 3, 2023 Share Posted August 3, 2023 can't beat nos if you can find it. If I remember right, I believe the auto version will work too by just not plugging that second plug into anything. https://www.ebay.com/itm/225185170978 Link to comment Share on other sites More sharing options...
TurboedMJ Posted August 3, 2023 Author Share Posted August 3, 2023 Thanks. I believe you are correct about leaving the trans TPS unplugged. Link to comment Share on other sites More sharing options...
cruiser54 Posted August 3, 2023 Share Posted August 3, 2023 ^^THAT^^ is a fact. How is it being determined you are in need of a TPS? Link to comment Share on other sites More sharing options...
TurboedMJ Posted August 3, 2023 Author Share Posted August 3, 2023 Previous owner somehow wired up an ho TPS (converted my whole top end to HO). It's making my truck run funky at idle Link to comment Share on other sites More sharing options...
