Nightmare getting my car running again
Now the car starts will tick over and also rev to full revs slowly, put the throttle on fully and it just wants to die. When I do a paperclip test the codes coming out are
66 - Carbon monoxide (CO) Potentiometer - High Voltage
73 - Air flow sensor Low voltage
It does sound like an air problem
Is the air flow meter on the pipe from the air filter? whats it mean by low voltage does that mean its a fulty sensor?
Help please, this is doing my tits in

Join the club, i'm rubbing low voltage on both!
The thing is, the CO meter (lambda) runs different voltage, according to the amount of oxygen in the exhaust compared to the ambient oxygen level in the outside air. The greater the difference, the higher the sensor's output voltage.
Not sure whats causing high voltage, crappy connector somewhere? Have you tried cleaning the CO 3 pin plug?
I have low AFM voltage, getting another 1 tomorrow, going to try that.
