TPS..

Hey guys, starting to develop a intermittent problem on my 96. Cruising ease into the throttle it will go just past 3/4 throttle then just kick out of lock up. If I go WOT sometimes all is well others spark knock ease out a little it goes away and it pulls harder than at WOT. other day I had it just key on with my torque app on easing into the throttle 3/4 I wasn't even at 50% go WOT 91%. TPS finally saying it has had enough of life or wiring issues? Fuel economy has been suffering too.

Thank you,
Curtis

Have you pulled any codes? I'd start there before going any further. Fuel Injection Technical Library » How To Run a Self-Test

Sorry, it is OBD-II no need for that. I don't understand never seen one act like this. Sometimes its fine but only 50% and higher throttle. Ordered motorcraft replacement.
