Hi, I have a reoccurring throttle sticking problem.. I have tried a few kinds of lube but they only last a few days then it starts to stick again..

I have tried a type of white lithium grease once, WD-40 and a graphite dry lube...

Do ant of you guys know what the best option would be?? maybe a silicone based lube??

Thanks for any insight..

 

have you tried cleaning INSIDE the throttle body? usually that is what makes it stick.

on the OUTSIDE, you just want it clean, oils attract dirt, and dirt makes it stick

 

And WD-40 is NOT a lubricant.

 

WD-40 is the trademark name of a widely-available water-displacing spray developed in 1953 by Norm Larsen, founder of the Rocket Chemical Company, San Diego, California. It was originally designed to repel water and prevent corrosion,[1] and later was found to have numerous household uses.

WD-40 stands for "Water Displacement – 40th Attempt". Larsen was attempting to concoct a formula to prevent corrosion in nuclear missiles, by displacing the standing water that causes it. In the process, he arrived at a successful formula on his 40th attempt.[1] WD-40 is primarily composed of various hydrocarbons.


The long-term active ingredient is a non-volatile, viscous oil which remains on the surface, providing LUBRICATE and protection from moisture. This is diluted with a volatile hydrocarbon to give a low viscosity fluid which can be sprayed and thus penetrate crevices. The volatile hydrocarbon then evaporates, leaving the oil behind. A propellant (originally a low-molecular weight hydrocarbon, now carbon dioxide) provides gas pressure in the can to force the liquid through the spray nozzle, then itself diffuses away.

These properties make the product useful in both home and commercial fields; LUBRICATING and loosening joints and hinges, removing dirt and residue, and extricating stuck screws and bolts are common usages. The product also may be useful in displacing moisture, as this is its original purpose and design intent.

 

Thanks for the advise. Im going to take the thing off and give it a good cleaning.

 

It (WD-40) is not the best idea for a lubricant. You probably don't want anything on the springs as any type of oil/grease would ultimately attract and hold dirt, and just gunk everything up. I would clean the spring(s) thoroughly and ultimately, make sure it's 100% dry of anything.

 

Yeah WD-40 sucks! I used one time... Im cleaning the throttle body up right now..

 

wd-40 is great, although since you don't have an atlas missile, you're not really using it for its intended purpose...

 

Clean and dry is the best.
Use white lithium if you want that protection from rust and wear. But when it gets dirty clean it all off with carb clean or brake cleaner. and re apply.

I use white lithium.

 

No lube.

The spring is designed to run dry.

Clean it thoroughly and that's all it takes.

If you MUST lube it, use graphite powder as you would with locks.

 

Not your issue as others noted but related to this-

I use anti-seize to lubricate my aftermarket cables (omp and throttle). Works great and doesn't melt away.

 

I just went through this when my throttlebody started sticking back in November and white lithium grease has worked fine. If you have a recurring problem just get another throttlebody for $20 used or whatever.
