Full Throttle by itself !!!!
Discussion
Had a bit of a brown underpant moment last night...
It was a lovely day so I decided to go home from work at lunch and pick up the Cerb to spend my lunch break the best way I could think of... All was well, and I decided to take it back to work rather then go home again to pick up the daily hack...
When I left work it was raining (that will teach me to trust the weathermen!!). Damn and blast. Ah well, I decided not to take the longer route home after all, rather the shorter, busier route.
About half way home rolling up to some temporary traffic lights I realised that application of the brake didn't seem to be slowing the car as expected and in fact my speed was picking up... It all happened in an instant, but the next thing I know the car is snaking all over the road. Fortunately there wasn't too much traffic and I managed to keep it under control and on the black stuff facing in roughly the right direction. Dipping the clutch made the enging rev it's heart out, so my only option was to stall it..
So I sat there for a few seconds regaining my composure, realising that I was blocking the road. I started the car again and held it on the brake to get it to the side of the road to stop blocking the traffic. The engine raced again and this time the MIL light came on and a high pitched continuous beep sounded.
I eventually got home after putting my foot underneath the accelerator pedal and pulling it up a couple of times, after which the problem seemed to go away.
So my questions are:
Is this likely to be a stuck throttle pedal or some such thing? - I am guessing yes, so how do I resolve it? (I have seen the other threads on accelerators so I guess it's the same deal as follow the throttle linkage and clean / lubricate everything ?)
The MIL light stayed on for the journey home, but I stopped the car and started it again when I got home and the light went out and the beeping stopped - am I likely to have done any damage to the car? It did rev pretty much to 7.5k at one point, but only for a second or two.
The temp gage went pretty hot, really quickly, but I can't and don't usually trust it on my car as it does wacky things. There didn't seem to be any fluids leaking out of the car last night or this morning, so I think / hope nothing has gone 'pop!'
Anything else I should think of??
Cheers guys.

Sounds most likely to be a mechanical problem with the throttle linkage and/or cable.
Sit in the car and press the throttle pedal up and down a few times, what does it feel like?
Get someone to sit in the car and press the pedal up and down while you check the linkage on the driver's side.
Check the throttle stop locking nut on the adjuster (engine end of the cable) is tight.
Check the spring is still attached correctly.
If all the linkages appear to be OK, then I'd guess it's the cable itself. You can just replace the inner cable itself using a Mountain Bile brake cable from Halfords, tke the old one in to ensure you get the right length and end fittings, and be prepared to do a bit of soldering crimping to fit the ends. Or try Clever trevor, they probably do a replacement throttle cable.
It's highly unlikely that a short blip up to 7500 Rpm will have done any harm.
