Hi All,
After braking very hard on a roundabout pointing downhill I suddenly had a very restricted throttle pedal and could only get up to 40mph very slowly foot to the floor. I managed to find a place to pull into and as there was nothing physically interfering with the pedals I looked at the linkage under the bonnet and noticed there is one position that limits travel and another "normal" position with full travel, and it had moved itself to the postiion of limited travel. I am guessing this is for autos and is to stop it overrevving at various points/in neutral etc but it then switches back to allow full throttle in gear??
As mine's manual it wasn't attached to anything so I manually turned it's position and all good again, normal throttle with full travel. I'm not sure whether to glue something to it to stop it happening again (though I very rarely brake hard so hopefully it won't happen again anyway) or if there is a reason why I need to be able to turn the mechanism to this limited revs position ever again? Or maybe there is something missing altogether which actuates this that has been removed/fallen off the car - I wouldn't be too surprised - though I can't see in a manual why you would want to limit accelerator travel (unless with clutch fully down I suppose, but I don't need anything like that anyway)...
Interested to hear if anyone's had this problem before and how to solve it. Not the end of the world and not dangerous perse though I could think of scenarios e.g. on a motorway where I wouldn't want to lose power suddenly after sharp braking...
