Did the so called 'paper clip' test on my x14xe SRi earlier and it flashed the following codes, the question is what can I do to solve them?
19- Crank Angle Sensor, incorrect rpm signal
34- MAP sensor, low voltage
33- MAP sensor, high voltage
24- Vehicle speed sensor, no speed or signal
13- Oxygen sensor, no change in voltage
28- Fuel pump relay contacts, contact problem
47- EGR, fault.
61- Fuel tank vent valve, low voltage
56- Idle control valve, low voltage
63- Amplifier control signal, low voltage on cylinders 2 & 3
64- Amplifier control signal, low voltage on cylinders 1 & 4
71- Air temp sensor, high voltage
29- fuel pump relay, low voltage
17- ????????????
92- faulty hall effect sensor or circuit
93- quad drive module in ECU
I thought that this was a massive amount of faults to have stored on my ECU, so I disconnected the battery for 15 mins (which apparently clears the codes) and then took it for a drive for about 30 mins, and it flashed up the same codes. But how can I fix the faults? I derived the meanings of the codes from here http://www.topbuzz.co.uk/info/fault_codes/fault_codes.htm#gm
but it has no explanation of fault code 17, whats that about?
The only things I can fault with the car at the moment is it sometimes misfires and when starting up from cold and driving, the revs dont seem to drop in between gear changes and it doesnt idle at a constant speed sometimes.

yeah I might replace the earth strap as it is old and isnt expensive either so worth a try!

mine was misfiring a couple times on acceleration today, but only up to about 2500rpm under heavy load

Pretty much the same with mine, only misfires up to about 2000rpm when I'm flooring it. I'm going to replace the whole ground wiring harness, so it eliminates all possibility of it being that (if that doesnt solve it)!

took mine to vauxcare earlier on, there was the following faults from memory... 02 sensor low voltage, Idle control valve low voltage, VSS low voltage, and something else but i forget.
cleared the codes the EML is still on but the car seems to run fine, however seems very rich on fuel!!
im contemplating replacing my ebay special o2 sensor with a proper deer vauxhall one

Get that ECU wiped. Sounds like you have a load of old codes on there 
34-33 codes mean that the MAP sensor isn't seated properly. Give it a wiggle and put it back in.
93 means the ECU is fucked from my memory
