Thought the car wasnt spot on. did a diagnostic test today in my dinner hour lol. I know I need ro disconnect battery and reconnect as i havent done it since ive owned the car.
Have the following errors showing at the moment tho:
13 - oxygen sensor - no change in voltage/open circuit = I have just replaced this so should dissappear once disconnecting battery
19 - Crank Angle sensor - incorrect RPM signal - got s spare, should i swap it or just clean it up?
22 - Throttle potentiometer sensor (TPS) - Low voltage= whats this and where?
35 - Idle stepper motor - poor or no idle speed control = I have one of these to put on. (Idle speed control valve yeh?)
67 - Air flow sensor, hot wire meter - signal is outside normal operation parameters (out of range)
68 - Airflow sensor, hot wire meter - Faulty air mass meter signal, incorrect frequency. - does this mean its fooked?
Any help would be much appreciated. Car drives ok but idles a bit high sometimes and can be a tad jerky from cold.

Air flow sensor from what i have been led to beleive would account for the jerkyness from cold.
They are alot from vaux tho, ring autovaux to get em cheap!
IIRC The crank angle sensor will always show as the engine is off i.e the crank isnt moving..
Not much help but hey every little
