My TPS will not stay adjusted, it keeps coming loose. I adjust it as per the instructions on Stinger's site, but it will not last for more than two weeks before it needs to be adjusted again. It does not become loose enough to fall off, but just enough that it comes out of adjustment and will shift with throttle movement or slight pressure from my finger. When adjusting it, I have tried just snugging it up, and also synching it down and regardless it will work its way loose. It has small locking washers on it so I am not sure what else to do to help it stay put. Any suggestions?

Are the screw holes stripped? Those are pretty small screws/threads and they thread into aluminum (soft metal).
Maybe try new lockwashers and some Loctite and see how that holds.

Is screws actually loosing up? if so Take evintho advice. If just changing replace it. I have seen the center of the tps strip out and adjustment keep changing. Maurice

Thats hard to believe. Are the screws bottoming out before the Sensor is tight?? Check how far the screws go in Without the sensor then measure the distance. If its the same distance as the thickness of the TPS then use a small washer. Dont use LOCKTITE. If the sensor has to be replaced down the road it will be a bear to loosen up. I use ALLEN head screws in place of the stock ones with Lock washers and small flat washers. Are you sure the body of the sensor is moving?? Also check that the shaft can rotate the sensor and that the sensor rotation is not out of RANGE mechanically. :bigthumbsup:bigthumbsup:bigthumbsup

if the screws tighten down use white loctite to help restore the threads and keep it from comeing loose also

Sweet! Thanks everyone, this is looking promising. I pulled the TPS off yesterday, the screws still seemed somewhat snug. Put the screws in without the sensor and the distance was just slightly smaller than the thickness of the sensor itself so I am hoping that is what my problem was.

Found some shorter allen head screws along with a thicker locking washer and it seems to snug up much better. The allen heads are nice and make it easier to get more pressure on the screw versus the phillips head. They are not any easier to access, but allow for better tightening. I will update in a couple of weeks, hopefully with good news. If not, loctite sounds enticing. I am guessing that white is the weakest strength?

Good job 7. I hope the new bolts work out for you. Just a quick note: white locktite is a pipe thread sealant, NOT a thread locker and it probably will not do much to prevent a bolt from working loose. If you need to use a threadlocker for a bolt that you need to remove later, use blue. Red and green BOTH require heat to break the bond. Blue is not that hard to get loose but works well in most applications to prevent bolts from working loose.
