My throttle hung up at 5000 RPMs while going down the road. I cut it off and pulled over. Got out and popped the good and the throttle cable looked fine to me. I pulled back on the gas pedal, crunk it up and it idled fine. Now, any pushing on the gas pedal (even just a hair) and it sticks. I have to put my foot under the pedal and slightly pull back before I press the clutch in. Any ideas on this?

 

Carpet, floor mat, insulation or nearly frozen pivot at the gas pedal hinge above your foot.

 

Maybe a broken spring in the throttle pedal? Or it could just need some WD-40.

 

Cables do wear out!!

How does the linkage work if the cable is disconnected ??

have you looked in the cab to see if something is causing this problem like was said.

When was the last time the linkage was lubed.

Why did you have the engine rpm so high??

 

inspect all of what has been suggested already, but also check out your intake and make sure it's nice and clean. when i got my truck, the PO never cleaned the intake and the butterfly was caked with carbon - causing the pedal be hard to depress and restricted how fast it came back up. at least you'll have a clean intake if it's not the problem

 

Def check the butterfly! Then lube your linkage

 

def check every thing above ^^^ and also check the spring the throttle cable connects to as well, mine was super gummed up (still have to clean it all the time) and my pedal was hard as a rock and super slow to return usually used my foot under it to push it back up, also why so high?? you're gonna blow the head like that lol

 

Definitely keep it under 5 grand besides formula cars and street bikes not too many inline engines like high rpms

 

yea, street racer keep them under 4. between 4 and 5 is HG kill zone... unless you're doing a hill climb when off roading, and even then, don't do it very long.

 

Yes sir good advice there! I don't dog it for more than 5 to10 seconds when hill climbing. There really is no need to go over 4 grand unless you built a race machine. If I'm not mistaken the 22r starts to diminish in horsepower and torque at about 4 grand anyways so no need to run it that high

 

20r, 22r, 22re, even the v6 as well, these engines have low end torque, after 4k you're just wasting fuel and risking lotsa $$$, learn from this my mistake on not listening about how sensitive these engines can be, they're tough, but do need to be respected
(also "ma'am" is more appropriate than sir personally)

back on topic... best way to clean your springs and linkage is use brake parts cleaner and a tooth brush, then oil it, use engine oil not WD-40, tho WD-40 is fantastic, it does go away with heat after some time, and then your linkage will be dry

 

Yes ma'am haha

 

could also be a vacuum leak my celicas throttle stuck because I have a supra throttle body and it didn't seal correctly so I had to put rtv around it and it fixed my problem

 

i agree that a vacuum leak would purpose a problem, but then he would probably have brake problems. how do your brakes feel? if they're hard (no assist) then its deff a vac problem. also since vac line is under a dollar per foot its nice if you get all new, then you don't have to pinpoint a leak lol

ps - get 2ft more than you think you'll need, you'll be surprised on how much you'll actually need haha (i needed over 6ft, but i wanted more slack in some areas)

 

I had a vacuum leak on my intake plenum where my throttle body is and I never noticed hard brakes or anything I wasnt driving the car enough when it was throttle was sticking to notice

 

it does depend on how significant the leak is, and where the leak is coming from. but brake boosters work off of vacuum assist, if theres not enough vacuum to assist a hard pedal occurs. it might not be that significant of a leak to be bothering the brakes enough to notice, doesn't hurt to check tho

 

Sorry guys. After about thirty minutes, I found the problem.
