Throttle cable- B*gg*r it.
Discussion
Oh well-it had to happen.I am posting again because symptoms seem to be different to the posts I found by searching.
My throttle cable has gone tonight-Can this be fixed quickly?
(Its truely excellent timing as we are off tommorrow as a family on the annual National Trust Firework event-a family tradition stretching back 19 years and my daughter is traveling back specially from the North with friends in tow tonight-thing is without the TVR we can't all go-which will put a major crimp on the event.)
Symptoms are
Throttle pedal appears disconnected-BUT it did not drop to the floor as described on other threads.It recovers when I lift off the peddle which is odd.
Popped the bonnet and you can go as fast as you like if you sit on the engine block and rev her manually so there's nothing wrong with the engine.
Urgently need some help folks

Yes you can replace the cable yourself. I have the instructions you just need a spare cable from a TVR Dealer. If you popped up to the TVR Centre this morning they probably have a spare.
The instructions are:
you need
8mm spanner
14-16mm spanner
17mm spanner
6mm allen key
5mm allen key
13mm socket and extension
torque wrench
side cutters
cable ties
remove the air box.
undo 2x6mm allen bolts - engine bay and release old cable
cut any cable ties
in footwell
remove metal pedal cover2x5mm allen bolts
using a 13mm socket and extension release the old cable from accelerator.
cut cable ties
tie new table to old cable with duck table.
Pull new cable through from footwell
attatch new cable to accelerator with 40mn of torque
reverse all previous steps.
I am told thats how it works. Others many know better instructions.

Brilliant help Maddog-really appreciate it!
All now sorted-but it turned out to be something different,my diagnosis was crap. Just for anyone else that gets the problem the spring clip got knocked out of the pin linking throttle arm to the vertical link and the pin had dropped out.
You can see the joint very easily as it is midpoint on the head and the airbox is cut out around it to allow the joint to move. It looked fine because with the throttle in the rest position everything lined up-if I'd had an eight foot articulated leg last night I could have pressed the throttle and seen it was disconnected. Took about ten minutes to find the pin and the clip and re-install this morning.
Family re-union rescued!

Excellent Steve, glad to see it turned out to be a quick fix, phew! Have just got back from the 3 hour long round trip to get my son, the M50 is a lovely, and usually empty stretch of tarmac - as I accelerated past the last visible car, I thought of this thread and wondered what would happen if mine suddenly snapped, how silly would I have looked, as the last numpty gave me the hand bean gesture for having the audacity to overtake him! 
I had just overtaken a few people on the A40 when it happened last night-luckily just before my turn off.Even so I had to do the last 300 metres at 5 mph with the emergency lights on.Lots of friendly guestures from passers by -at least I think they were friendly,there certainly were a lot of them in any case.
TVR's ....don't yah just love'm

No maddog it was completely missing-as was the pin.I think what happened was that I must of knocked the clip out when I removed the airbox to get at that pesky fuse between alternator and battery the day before,which is where the trouble started.
The pin and spring were both still lying in the engine casing below the throttle link-I was busy bending a paper clip to make a temporary link to get me to Barnet when I saw them.I got them back using a magnet.Barnet were amused I had managed to get the pin round the right way but would not consider my application for a job as a mechanic.

OK, so how do I remove the airbox? I undid the 2 clips and the 2 bolts on top. I can't see/feel any bolts or clips towards the rear. Do I just ease the whole top off at this point?
Thanks.
Thanks.
You do.You need to ease it of the air intake ports and forward about 2-3 cm to clear the rear of the box and then lift it out -its a bit of a fiddle as its a tight fit but it will come out.If its been raining look out for water getting to the exposed air inlets. Oh and it might be easier if you pull out the black tube at the front of the airbox first-its just pushed into place.
You got problems to?
W need a Haynes for T cars.
By the way I think there is more of this in the sticky at the top of the page.

There is another clip at the back that needs to be released before the you can remove the airbox.
