Re: Throttle stuck, almost died (Glutamine83)
this happened to me twice! ... the first time i traced it to the black plastic tube/throttle cable guide thing (very technical description).. it had detached itself and was jamming the throttle open. The second time was when my cruise control decided to activate itself and suck the trottle full open... :eek:
... i also had i similar experience in a VW beetle whilst driving round Hyde Park Corner... but that's another story!

Re: Throttle stuck, almost died (cheese)
my floormat may have been the culprit
i pulled the carb off, rebuilt it, as well, we inspected the throttle cable and the return springs.........
cheap )(*$)(#) floormats

Hi guys,
Just happened to me too this evening. Passing a car and gaz pedal almost on the ground, then the car kept accelerating... Pushing on the brake pedal like hell as I didn't realise what happened. Then trying to go back to neutral but for any reason (me stressing I guess), it did make it. brake pedal on the floor... then quick reasoning... what can I do (here in Europe we are used to manual gear, so in this case I would just go to neutral or use the clutch). Anyway I turned the engine off... smoke all around the car...I probably used all the brake pads.
work for my friend mechanic :-)
after stopping and getting my heart rate to approx normal, opening the hood, I realised the throttle was stuck.
How can that happen? Which test can I perform ? Remedies? Two spring on the throttle? Replacing the accelerator cable?
What happens if one turns the engine off while not in neutral? Am I risking the whole transmission system
I better take some pills to go to bed or a whiskey:-)

I install a pedal stop on the floor so that the pedal stops before putting carb throttle plates, arm and cable assy in a bind. I always test the throttle at full pedal when hot and engine off to see if there is any binding. Catch you catch everything maybe not but it helps.

Maybe an old thread riverracer, but it still applies...
check your throttle cable and linkages to see what is binding. Could be the carb needs a good clean. If not used for a while, can get a "gunky" film on the moving components.
obviously check the spring returns and verify the throttle transitions without any stickiness.
I had a similar issue (throttle stuck full) during a track day. Could not work out what caused the issue until viewing in car video footage. Looking though the rear opening of my L88 style bonnet I saw my engine jumping up about 2" everytime I floored the gas pedal. Then I realised my engine mount was broken. 😨
