Vauxhall Mokka 1.4 Petrol MOT October 2026 ulez complaint . some service history . alloy wheels and good tyres. Car has developed a misfire and runs rough on idle . Partner had it scanned and fault code was p0300 misfire . We were told it needs spark plugs and coil pack but it's no longer needed as he's getting a company car so he does not want to put any money into it Long MOT. Almost years long. It drives, just runs rough.
