SPArKy_Dave 8,883 Posted February 7, 2014 Could be a million things, from fuel supply, coil pack, map sensor, torque converter, transmission binding up, and so on. Is it running hotter than normal? Using more fuel? I'd start with checking coilpacks, leads and plugs. Check the faultcodes too. 1 bear351c reacted to this Share this post Link to post Share on other sites
