Hi Nodge, it was a long drawn out pain in the a$$ , I went through the list of things suggested or that I had read up on and spent quite a bit of money on parts that made no difference, but as it was intermittent for a year or more before getting considerably worse it was difficult to pin down, with hindsight I would have just bought a couple of 2nd hand injectors in the 1st place ! it goes like a rocket now, especially with the Rover Ron box back in as I thought that was masking the problem.
