Quick TPS question..XT6

[Bucky92]

I am looking for an opinion ASAP..so this is kinda posted both here and XT6.net..but usually I get answers quicker here....We are in belief that my stalling issue on my 88 XT6 is caused by something faulting my TPS..I pulled it to check it and also have a fix but before i break it open...would the fact that it was missing one of the screws that hold it on be causing Rockys irratic deceleration stalling?

 

TIA

If it allowed it to *rotate* on the throtllebody, I suppose it could be. Perhaps the idles switch is not making contact at the right point? Any other type of TPS problem I would think youd get a code. Do you get any codes? I had weird stalling on deceleration or coasting problems when my speed sensor went out, but that was on a Legacy.

in general no. if it's too loose and not holding it then it could. but one screw is plenty to hold it in place and in alignment. as long as it wasn't loose...and in that case it probably would have been maxed out in terms of adjustment and the car wouldnt' have ran at all, i would imagine it's fine. mentioned this at XT6 but i wouldn't go cracking it open unless you had a spare one handy. hasn't been that long ago since we've seen a "hey i jacked up my TPS and need another one right now" post, hate to see that happen to you if you need this car.

Well I tested it acording to the test proceedure..and its testing good..Gary as you said about maxed..actually after I repositioned it ..it was almost maxed..so anyway..I positioned it so it opens where it is supposed to ..we will see if it helped..cleaned the external contacts before putting back on...wont know till I take it out on a run..since I am in the middle of doing some more body work..that is out of the question for now...Thanks for pointing me to that fix though!
