Sticking throttle
Hi guys, I've got a '99 Ranger, 4 cyl, automatic. If she sets for 6 to 8 hours, the pedal is hard to push down. It only happens after she sets. The rest of the time she works great. Any ideas? Thanks.

Hey Bob,
Sounds like to me that something possibly needs a shot of lubrication. After you hit it hard the one time does it loosen up a bit? You might try a few blasts of white lithium grease at pivot points just to see.

[updated:LAST EDITED ON 23-Jul-02 AT 11:36 PM (EST)]I just fixed this on my 97 Expedition. I took the throttle body off and cleaned the entire housing with carb cleaner. It seemed that there was a buildup of carbon which made the butterfly valve stick to the body.
Be sure to get a new gasket... $3 at any parts shop.

Yeah, Ron, after I tap it the one time its good to go. It just sticks after it has set a good while. It doesn't stick after I tap it from then on until she sets a spell.

I was thinkin about this after I read Mike's post and he's probably on the money. It's been a long time ago but I had to do the same to the butterfly on the throttle body in my Corvette. It wasn't a problem after that. Bound to be either that or a linkage somewhere that is either dry or binding up.
At least it makes sense to me....

Varnish is building up on the throttle butterfly. I've got the same problem on my '98 2.5l Ranger. The first time I cleaned it I shot Gumout up the intake while running. Worked like a charm. A week later I had to replace the IAC (Idle Air Control) because I'd wasted the seals with Gumout.
$55 part, don't let it happen to you.
I've cleaned it out twice since then, when I've had the intake apart for maintainance or repair. Just don't shoot it while running. Work the throttle by hand and spray the b-fly. Should take care of it.
