Possibility bud. I think Jano tried a different but i will borrow my mates one when i next see him to be sure.

Also have you tried a new coil yet? you said yours is only a couple of years old but iv had 3 group a's die in less the a year!
Yeh checked and cleaned all plugs, we even tried a whole new loom so defo not a loom issue.

Is it on a stock crank pully.

I was running an alloy one but switched to standard pulley recently on the hope it was a trigger issue, but no better.
After Ford Fair i will be throwing the towel in on my knowledge and handing it to someone reputable to try sort again. Just bought a new house so money is tight at the mo!
Thanks for all your input guys, i tried the fresh crank sensor yesterday hoping my last one was faulty but still no better. fitted and gapped new phase sensor tonight so will see how that works out on the way to silverstone. Camping tomorrow but as usual no track time sunday as every year my car throws in something new to make me hate it again lol.
Cheers chaps.
