Just got my 1997 f1540 4.6 4x4 back after my guy did alot of work....intake gaskets, plugs,all hoses,master cyl,all rear brakes and em. cable....etc.Now driving it home it sputters/surges in overdrive(where its most noticeable..) and threw a p0122 code when I restarted after a gas stop(with pressure in the tank when taking off cap...???) The sputtering/chugging would seem to be related to code for a throttle position sensor...should I just replace it or should I look somewhere else?....thanks

 

I would first make sure it's connected good and the harness is in good shape. If all that checks out I would replace tps.

 

Is there a "wrong way" to install the tps?Seems there is a tang on the inside that should line up with the one that came out.....

 

Ok, Tried to remove the 2 tps screws with no luck... read up on ways to get them off..cut slot in screw/heat up locktite/grind head off...but I cant find a spec on replacement screws...some say 7mm...8mm...one says m5x30mm.Does anyone know what spec the screws are?I dont want to start til I have them....thanks

 

Those usually will only come out with a little 1/4" impact. Without an impact, they'll strip right out. In the past, I've been able to get a small pair of needle nose vise grips on the screw head enough to break them loose.

Sizes, -

5mm, - the heads are 7mm, - in bolt head form, the thread/shaft is 5mm. Personally, I use COP bolts to secure the TPS, -

 

By the way, here's a better bolt to replace those with, -

If you do, (and that's the exact size you need) just don't over tighten them. They only require light torque and that bolt I posted will go in snug, - meaning you may not be able to run it in all the way with your fingers. That said, - light torque is all you need and she'll stay.

 

I believe that length will work, - I'll confirm it later today, - it may be 30mm.

 

Thanks for the replies...I'll let you know when done!!!

 

tps installed(after drilling out top screw..) A trick I used on the bottom tps screw was to take a soldering gun to heat up the locktite and the screw came right out.The tps took care of the sputtering/shifting and cel code.
