Have you guys tried checking the Oxygen Sensor? its positioned on the exhaust manifold right at the front and top of the engine bay.

I had issues with intermitent juddering at low revs, and stalling after high revs as well. Simply checking the connector revealed corrosion on the pins, and after a bit of cleaning then all seems well. The connector is an unsealed type and therefore can suffer from the elements over the years. I know its a simple fix, but well worth a try. Also meant my fuel consumption returned to normal after it was running far to rich.

The sensor itself is difficult to remove, and the engine needs to be hot to have any chance. However, to test functionality then simply unplug, rev the engine and you will hear the engine struggle as it returns to idle. Re-connect and all should return to normal (its a closed loop control system....and all that jazz....).
