My throttle pulley is sticking. I can unstick it by oiling it with PB blaster and that fixes it for about a week. When it sticks and causes my truck to idle at 1000 RPMs, I can also unstick it by lifting the gas pedal.

Is there something else I can do other than PB blaster the thing every week?

I tried loosening the throttle cable just a tad, but it's all the way loose (and still a tad tight, but not so much it holds the throttle open.)

Your cable could be frayed

Embfixer

Take the air intake off and inspect the throttle body (called the butterfly around here for some reason) for damage and gunk. Most likely gunk. Clean it with a brush and solvent.

The cable may be sticking or binding/frayed inside as aboved stated. Disconnect it and check for the throttle sticking.

DupermanDave

Did that. I should mention it's a used, but newer, TB. I cleaned it before I installed it. It seats properly (which is the problem I had with the old one.

I also considered the frayed idea, but I removed the cable and made sure it was loose, and then was able to seat the butterfly valve and unstick it by hand. I'm sure it's at the pulley.

hmm, maybe some white lithium grease??

DupermanDave

that may be the way to go. Would heating it up make it sludgy and make it squirm its way into the socket?

874runnersr5

socket, as in that little bar linkage that connects the two things?

Hmmm I'm having the same problem.
If I tap the accelator pedel, the idle goes back down. It is a pain.
I would be interested in what you come up with for a fix....

FIX: Tap accelerator pedal once.

i was having the same exact problem and i found mine to be sticking to where it actually rests when it is in idle position. i would just pull the throttle cable housing thingy<--while my engine was off of coarse! and spray it with WD40 every time i went to drive it for like a week and it went away....

DupermanDave

Yeah. Socket, bushing, whatever you want to call it.

I think I'll try 2 things. I'm going to use some graphite lube for the cable and some lithium grease for the pulley. Thought I dont think the graphite lube will help, as it's not seeming like a frayed cable.

WD-40 is so thin it doesn't work well as a lubricant. PB Blaster is pretty much just for unfreezing parts - probably worse than WD-40 as a lube.

For the butterfly shaft, 3 in one oil is probably best - just a drop at both ends of the shaft inside the throttle body and move the throttle to work it in. For cables and such, I've become a big fan of Maxima "Chain Guard" - it's a motorcycle chain lube with great adhesion and lubricating properties. I've also heard good things about Bel-Ray's original formula "Chain Lube". A local motorcycle shop should have one or the other.

Both of those are the old kind of lubes, not the new dry wax types which would not work well on a cable. Maxima's dry type is called "Chain Wax"; Bel-Ray's dry wax type is called Bel-Ray "Super Clean Chain Lube"

For applications that get exposed to water or grime, like the parking brake linkage or the spare tire winch, a dry wax type lube might be best. The chain lubes might be worth a try, but my long time favorite is Boeshield T-9, developed by Boeing for protecting aircraft from corrosion, it both lubes and is a dielectric sealant great for protecting wiring:

haha i had the same exact as you and just like demonwithin i used WD40 for about 2 weeks and everyday, there has been no sign of it coming back. the chain lube sounds like a great idea for your problem though... itll make everything look greasy though, and it attracks every little piece of dirt.. oh and its extremely hard to clean.

DupermanDave

PB blaster was all I had in the toolbox. I know it's more of a liquid wrench, but my WD-40 just spurted it's last spurt a few weeks ago and just haven't bought any more.

I'll try some of that chain lube. Is that for using on the cable or the throttle pulley? Or both? If the chain lube picks up dirt and grime, it would be bad for the cable because it would get all gunked up and then cause it to stick some more.

the WD40 wasnt realy for lube it was to break down the gunk on the contact points where it was sticking!

kawasakimoto_7

yes the dirt and grime would be bad but i dont know how much dirt and grime you could actually get on it, i just know it attracks a lot from experience with it on dirtbike chains

I swear by this stuff for these kinda lube job's. Doesn't turn gooey, lasts a long time.

mannnn that looks like it would be perfect...

DupermanDave

That looks great. I especially like the smaller cans. Can you get this at autozone or hardware stores like Ace?

-edit-

found it. On their site they have a shop location finder.
