Hi people. Having an issue with my valver. Has run perfect for the past two years. However the other day its started to judder and struggle to keep going and ended up kangerooing down the road. Once stopped the fuel pump became very noisey and almost cut out with the revs dropping. I have since changed the fuel pump and checked the lift pump in the tank. All the fuel lines have been cleanedto. The car started fine after repreplacement and ran perfect at idle. The original fault still exists. I have now replacd the ignition coil and fuel pump relay. The car ran very well for a mile or so then the same fault came back.severe juddering and kangerooing. I have checked the dissy cap and leeds and are all in good order.

The problem i seem to have is loss of spark. If i earth the king lead to the engine it will spark once then die off.

could this be the ignition amplifier or the dizzy packing up?.all earth wires and connections seem in good order.the car has been maintained regardless , timing is spot on and before this issue the car ran superbly. Is there a way i can check the dizzy and ignition amplifier?

thanks guys
