In this case it was caused by the top of the pedal getting stuck in the bulkhead soundproofing after the carpet had been removed. "But the best cure is prevention – whenever you’ve been working on anything around the throttle, before you shut the bonnet it pays take a step back and look at the situation. Is there anything that could jam the butterfly open?" The same goes for the pedal end too!

It was a throttle return spring which was seated wrongly and unhooked itself. It happened once in a McDonalds carpark, and once at a major suburban Adelaide intersection. Luckily, it happened on a green light and I was at the front of the queue. That mini never took off so quickly in it's life! I was turning a corner, so I changed gears once or twice to keep up with the revs and then switched off and pulled over. A scary experience for an 18 year old in busy traffic!

With the bulky side of the air filter now sticking inwards, both throttle blades caught at about 3/4 throttle, while I was turning right across a major intersection in 3 lanes of traffic. The resultant powerslide as I panicked and then turned off the ignition almost took out two lanes of traffic, slammed the car sideways into the curb (cracking both wheels)...and a serious brown-trousers moment!

My Aztek had cruise control problems...It would not turn off and when I braked it thought I was going up hill so it would try to accelerate to maintain speed. First time was with the family on an open highway. Second time was on a highway coming up to traffic.....3rd time ....month later was in the city coming up to a red trafiic light. Nobody took me seriously until I dropped the car off at the GM dealership and "gave it back". Left my buiness card and told GM the car is theirs until they solve the problem. EVERONES safety was not worth it. An hour later I received a call. They found the problem. A small locking ring holding the cable onto a bracket came loose. Every so often it would slide down the cable far enough to jam under the throttle pulley. Anyway fun it wasnt if it ever happens again I will insist they take me more seriously the first time. Thankfuly my track experience kepy me calm and prevented incident. .....I turn off the ignition. But when I share this with people, most are horrified and ask how on earth did you manage to stop! Which brings another issue to hand...driver training and education. Very few had thought that turning off the ignition would have been a solution if it happened to them!

Its happened to me a few times. Dodgy throttle return spring on the ol' 76' B1600 mazda 'u bute' ute, no serious problem just clutch, brakes, curb. However the 83 Alfa GTV6 was a different story...not so fun, more scarry and requiring much faster reacton to avert major disaster. A bracket in the throttle assembly was interfering with another component causing it to get stock wide open and this was induced by work done earlier. Moral is, check before you drive! Hopefully I will be more careful with the R32 GTR because based on previous experience this would be much harder to 'catch' in time...

I was 18, had just recieved my blacks and finished working on an old 86' Magna. The second drive out i decided to give it a squirt, but the squrt never ended. I found my self traveling down hill on an 80Km/hr rd. Standing on the brakes worked... till they faded. Switching off the car and throwing it into neutral worked sort of. I think the engine was overheating by that time so hotspots in the cylinder keped it ticking over in a lurching kind of rumble. 5 mins later it was off. The cause? The throtle cable had picked up dust on the exposed end. Previous owner, elderly lady never used full throtle. I did! It can be very wild.

I learnt to drive on a motocross track in an old VW Beetle about 20 years ago. I was bumping down the back straight (I was about 12 years old) only to find the throttle stuck wide open and a 180-degree corner approaching rapidly. I stood on the brakes (without much luck in a '58 beetle) then hit the kill switch. I ended up skidding over the back of the banked corner and flattening a few bushes - I thought it was great fun! Unfortunately that was not the last time it occurred - those Beetle throttles had a habit of jamming when bouncing over REALLY rough ground. It was never quite as exiting as the first time though.
