threw in a new battery and started the car it idled till the temp came up to hal way, as i was sitting in it watching the temp i felt a slight blip, ie a miss on idle, thought id touch the throttle to see if it disappeared and when i did the cel came on, checked it and it read code 22.
Hope its just a knock sensor, as recently after a spirited run, i came off a roundabout in 3rd low down in the revs and accelerated, for a spit second the car felt like it hit a brick wall and the cel came on and straight off, so fast i barely saw it. got the car serviced the day afet and saw nothing till now.
