right left work as normal today and the car ran very rough, on the motorway i held down the clutch to listen to engine and it stalled! restarted and carried on to junction, stalled again so i pulled over, tried to restart it and it went first time and the roughness had all but gone!
so finished my my ride home and checked under the bonnet even though i didnt have a clue what i was looking for!
didnt see anything so started her up to put her away and she sounded great again. so my question is if anyone can help is what the hell happened there then
ps dont know if its important but the battery gauge had a higher reading than normal 15plus (4ltr 92)

Could be the alternator diodes playing up sending AC where only DC goes.... or any of about 50 other things....

Does that car 'kangaroo' as part of it's rough running... If so you could check that the vacuum advance hasn't come loose. I had a problem that sounded very similar to this some time ago.

The vacuum advance lives by the distributer cap and looks a bit like a flying saucer. You could also check a thin pipe that runs between the vacuum advance and the plenum to see if it has come adrift or is blocked...

Hope this helps

Cheers

try checking that the earth connections to both of the fuel injector banks are not loose. i had similar problem - rough running, difficult restart and then all of a sudden everything was fine when the connections touched again - i was running on one bank of injectors sometimes. no idea where the connections are, Tower View fixed mine - Steve Heath, could you help out on their loaction?

Check earths and the alternator diode thing Steve reffered to...I doubt if the problem would fix itself!

If it was wet when the problem occurred, you should check that there are no holes or splits in the large air intake hose (N/S of engine compartment) at the front of the engine bay. I have heard of water getting its way in there...

Unless this type of problem manifests itself at the garage (they almost never do), it will probably be almost impossible to diagnose. You can only try and eliminate the obvious stuff...earths HT leads etc.

Good luck!

mine did something similar when the stepper motor was dirty/playing up/something not right, check that.

ah - you have been deluded into the classic state of - "not sure why it went wrong, no idea to the real cause, it seems ok now....so best leave it alone....it won't show up when i ask the local garage anyway" but deep lurking beneath your bonnet now lives a special tvr gremlin. from now on you will never be able to get rid of him. he will nag forever at your mind and suddenly appear without warning when you are at a traffic lights with a white van on one side and a 911 on the other. the 911 will disappear, the white van man will laugh at you as your personal tvr gremlin rears his head in the shape of your griff loosing all power and simply refusing to move.
been there..done that..got the t-shirt!

there was a string on the 2nd of December about this - he experienced exactly the same problem down to the clutch thing. It seemed to be something like water contacting the sensors in the air intake..

Yes, that's right about the air intake!

I have heard about it also and that is why I suggested looking at the air intake hose.

Just trying to help.

Good luck!

it was probably my experience that started this one, the bonnet would rub a hole in the hose, which is where the water gets in
