OK, I've changed the dizzy cap and rotor arm on my cav turbo now. The ones that were on actually looked like they were reasonably new but i changed it anyway. The car is a little bit better but not a great deal. My next thought is that the timing could be out. I also have a problem with the Temp Sender 'thingy' so could this be the problem?
I want my turbo to run proper so any help would be appreciated.

Maybe I'm stating the obvious, but since you have the ECU reporting a fault, isn't it reasonable to fix this first before anything else?
If the ECU doesn't trust the coolant temp reading, then it will use a fixed value, erring on the side of caution. most probably it will assume that the engine is cold all the time. That would result in reduced performance and perhaps increased fuel consumption.
Well it's not hard is it. Just walk into your local vx dealer and ask for a coolant temperature sender for a *reg 199* cavalier 2ltr 16v turbo.
PS it ain't the pug you need, it's the sensor that is screwed into casting just below the thermostat. BTW these things have a shamfered thread. Don't try and do the thread all the way up as you will end up shearing the sensor as they are hollow.
I bought one for my gte 16v, the vauxhall part number is 90510183, TEMP SENSOR #2 - £20.27 inc V.A.T
I know i dont have a turbo, but i'm 99% sure its the same part, they were used well into the mk3 astra aswell, so availability shoud be good. Obviously you are going to a vauxhall dealer so you can check the above.
