the faults were

552: Pulse air circuit failure
122: Throttle Position
157/158: Mass Air Flow Sensor
211: PIP Circuit Fault
212: Tachnometer Circuit Fault
214: Camshaft Identification

he said all this could be down to a earth fault?

i dont know how the camshaft sensor is faulty else the car wouldnt work?
Ive tried various MAF's and TPS sensors but they didnt even make a difference and yes ive tried the RS1800 ones
