Hi mate, changed camshaft sensor its on the end of head above coilpack. Do you mean crankshaft? Brand new coilpack, leads plugs...... Tested everything for readings! Atm its behaving after removing battery power for 15 mins!! Can anybody believe this? Did it store a fault and loose it when power removed?? Seems odd but i spent 2 days solid trying to sort it and that seems to have sorted it so far.. Will b back to let you know.
