Duduglanza Posted February 4, 2017 Share Posted February 4, 2017 My car developed a problem out of nowhere. It stared missfiring and juttering while on throttle for the first few minutes when cold. It so bad that i cannot drive it till it warms up. Once it warms up its absolute fine. What can this be? Quote Link to post Share on other sites
