Sorry if this is an easy one, really limited knowledge.
After leaving the mini sat for 12 months, I started it up this morning to see what condition it's in.
The good news is after leaving battery disconnected, it started first time and all seemed to be running smoothly. However, when pulling out of the garage, the reverse gear engaged and moved back at a gentle rate, on a deeper press of the accelerator, the car revved at a faster rate (which the revometer showed) but no increased power went to the car.
Took it for a quick spin around the block and the car moves at a steady pace in both 1st and 2nd gear but power to wheels remains unresponsive to the push of the accelerator pedal.
