Thank you both. To reply to Arthur, I pulled the vac line of the FP regulator and is clean as a whistle no fuel leaking. I have given the car a good run after resetting all the codes, stalling many times and getting poor power at low revs. Check the codes again and got the following results.

Pin 8
code 4 MAF sensor
no other codes.

Pin 14
Code 1 All clear

I may have set off some of the previous codes as I have been checking plugs and coil and other electrical connection to make sure all were contacted well.

Does this now mean there is a faulty MAF sensor, can I check it out easily or give it a clean or should I bite the bullet and replace it?

Thank you Jim Y for your help, My problem does indeed seem similar to yours.

Mike
