Ok, I done the diagnostic on the car and got:
62. Intake air control valve position sensor
What is this and how do I fix it? Would this have an effect on the stepper and that's why it's not working?
Also after taking out the panel under the steering wheel I found out someone had a lot of fun with the wiring of the car!! Theres cut wiring pipes, insulating tape and wires all over the shop!! I think the alarm system that was installed was done by an amateur, so going to have to sort that lot out soon......
