ramy Posted September 6, 2013 Share Posted September 6, 2013 Hi all my deck being a pain at min , was having issue with loss of power so had throttle body cleaned didn't help , new back box as it was a bit rattly that didn't work , removed and checked cat hadn't collapsed but was fine , eventually replaced fuel filter n added a fuel treatment and all power returned so was happy , but after 160miles the issue cropped up again today , foot down n very little power n exhaust tone goes deep , in thinking now it may be the auto box not shifting down , does anyone have any ideas and does gear change rely on kickdown cable or vacuum pipes ,,,, please please help thanks in advance ramy Quote Link to comment Share on other sites More sharing options...

NIKH25 Posted September 6, 2013 Share Posted September 6, 2013 If you have MC1, there's one in the cat too. I'm sure I've heard of them failing without cel on. Quote Link to comment Share on other sites More sharing options...
