throttle staying open

[postalrm88]

i was driving the monte this past weekend and its going fine then all of a sudden after about 2hrs of driving i go to stop and my gas pedal sticks to the floor and the throttle starys open and the only way i can get it to come up is to basicly stomp on it and break it free has anyone ever had this problem before and how did you go about fixing it

you drove your car home with the gas pedal sticking? You have more guts than me. :shock:

do you not have 2 return springs?...it could be the cable itself if it was touching something hot while you were driving

Either your cable needs to be replaced, or your floor mat is sticking.

I will never ever ever run without 2 throttle springs ever again. Ive only ever usually run 1, but had it fail at the finish line of a 1/4mile drag strip. 472 cubic inches stuck at 3000rpm going 100mph is not fun.


Also, I had this happen in my firebird a long time ago. Throttle spring was fine, floor mat was removed, cable worked just fine, but after about 1/2 hour of driving the RPM's would get stuck at 3000rpm, but it didnt feel like the throttle was on. The tach and engine showed/sounded like 3000rpm, but there was no power until I stepped on the gas. Turns out my advance weights were sticking open. I took them off, polished them with sand paper/steel wool to remove the rust. Put the tiniest amount of lithium all purpose grease on, and voila, no more issues.

Take a look at the plastic sheath that covers the cable between the throttle bracket and throttle arm of the carb. Make sure it's not catching on anything.

I would still be checking everything out to find out what caused it and to ensure that it never happens again. I had the throttle stick in a friends truck while I was driving it and its one of the scariest feelings you can experience at 60mph coming down a hill to a stop sign. I would hate to see a car as nice as yours get totalled because of something small and easily avoided.

a stuck throttle isn't something that should be checked out with a road test... park it until you figure out the problem for your sake and everyone else's
