I'm away in Weymouth with friends my mates 2015 twin spark pp. is running rubbish coffin and spluttering low down. Any suggestions
Had you just filled up? Water in fuel? Unlikely but worth a try. Loose battery connection? Check all plugs/connections are pushed together? Could be one of the Air pressure sensors. Any fault codes?
Have you had anything done recently? Changed anything, like the decat? Is there a warning lamp? Funny it’s OK up top. TPS maybe?
