happened today on my way home from work, driving along and engine cuts out, problems are: 1. idle revs on about 500 2. there seems to be a consistant 4 second delay on accelerator under 3000 revs. if i get the engine above 3000 revs and accelerate rapidly on and off, works fine 3. wen accelerator pressed fully, will accelerate to 1500 then pause for a few seconds before continuing upwards, also keeps cutting out. any help would be very much appreciated.
