Oh God, help me!
 

Ok so some scary shit to have happen on the road, heading strait for a exit ramp. Gas pedal hits the floor, then goes farther, gets stuck to the floor and doesn't come back off. First instinct is wrong...clutch in to decelerate...this results in instant revs and bouncing off the rev limit. Turn engine off. I limped it back home by turning it on and off. Transmission pretty much regulates RPM for the rest of the ride home..I brake rpms drop.


Basically I need help. This all occurs after having done a oil change. When I stopped the car I had found that when i pulled the second spark plug wire to clean spilled oil i didn't push it back in all the way. I'm going to be tearing appart my intake to check the TB. I don't know what else to check...any advice. I don't think the Throttle cable melted but it has a lot of slack.

Is there an adjustment for the cable at the pedal, maybe that broke?

I don't know I took a look at the pedal but couldn't figure anything out.

Also does anyone know what position is most conservative for the throttle position screw?

wow dude. Glad you didnt ride the brake like the dude in his bimmer and crash cause he was too stupid to turn the key.

maybe the cable is snapped and stuck or something? I dunno.

beats the steering wheel coming off in your hands :hs:

throttle return spring?

if you pull the pedal back up, does the throttle plate move in the engine bay? can you get a helper to check it for you? that'll help eliminate a broken cable. but even if the cable were broken, the plate would default to closed, not open. you might have a stuck cable. we need to see if pedal motion corresponds to throttle plate motion.

my vote is on return spring. ive had this and my throtle cable fail before on my nissan not fun.

all is well the spring wasn't seated properly.

It had to be something simple. Glad it was easy to find. Good job shutting it down safely and limping it home. From what I've seen of stuck throttles most drivers don't think that fast.

glad to hear, and that you're safe

Good thing its not a diesel. I have heard scary stories about old vw diesels running away. Basically the engine starts sucking the crankcase oil up and running on that along with the diesel. Starts revving super high. You turn off the key and the DAMN thing keeps running! You gotta get it into the highest gear and get on the brakes hard.

that is why they call it deisiling :rofl:

now boost the damn thing already Tom!!!!

Not just VW's..any Diesel..

113's used to do it all the time, nothing more fun then trying to find something flat to hold over the air breather intake pipe as a roots blower is howling away :eek:

that's how I grenaded a bmw diesel engine at work a few years back... the turbo seals got fucked by some idiot never topping off the oil. basically they brought it to me with a knock that my co-workers were sure was fuel knock. I took it out for a test drive... it ran away.... there was enough oil comming out of the twin turbos to keep the engine running and it ramped up to 7K rpm (redline was 5K) before it blew. chucks of metal and a bunch of oil all over the fucking road.... it was nasty. 2006 535D with the M suspension and wheel package.

I thought that when you turn off the car it cuts spark?


Hey fuckfaces, I know exactly how a diesel works and the differences between a gasoline and a diesel car. I'm just fucking with you, but let's see how many 'OMG, di3zels dont use spark LOLOLOL' responses I'm going to get.

And I know that it's possible to diesel a gasoline car too. A buddy of mine bought a carbed prelude from an old lady that never had it above 2k rpm in the 150k miles she had it. After a spirited run, the combustion chamber was probably glowing from all the carbon buildup so it ran for an extra 30 seconds or so.

Yes it does...that's why the diesel can keep running. Diesels don't use spark they use compression to achieve detonation. Yeah the whole knock thing that everyone in our cars avoid is what purely runs theirs. Turn the engine off to cut fuel but it keeps going on oil.

That would be all kinds of scary.

I'm working on it scott! really...just ordered my MS. ^_^


One of the many things I keep thinking about for a DD is an old BMW or Merc. diesel to convert to bio. Else I'll just get a bike and enjoy the 80 mpg @ 80 mph.

Same thing recently happened to me. Turned out to be a frayed throttle cable that jammed up inside the cover. Luckily, the throttle cable isn't all that hard to replace. It basically just loops loosly into a groove at the end of the pedal. The hardest part was ripping apart the steering column and taking out the seat to make enough room to crawl under the dash.

if that shot was at me... i need that turbo back haha. than i need IC piping, and my dp fabbed.
