Andymac183 Posted May 8, 2017 Share Posted May 8, 2017 The car was in for paint and other bits through the winter and spent about 5 months off power completely. Now I can't seem to get more than 16mpg tops whereas 24 was more the average. Do I need to do the pedal dance? Will that help to reset the ECU? NO other alterations to the car in this time, just cosmetic...! Quote Link to comment Share on other sites More sharing options...
Ekona Posted May 8, 2017 Share Posted May 8, 2017 How are you measuring the mpg? Actual maths following a fill up, or from the OBC? No harm in disconnecting the battery for an hour to reset everything, then seeing what happens. Quote Link to comment Share on other sites More sharing options...
Andymac183 Posted May 8, 2017 Author Share Posted May 8, 2017 I'm just looking at the OBC to be honest. Might try the actual maths route as well but she feels like she's drinking a lot...! Quote Link to comment Share on other sites More sharing options...
veeg33 Posted May 8, 2017 Share Posted May 8, 2017 Definitely worth doing the pedal dance to reset ECU, reset throttle and learn again. If none of these helps, next step would be cleaning the intake system. Quote Link to comment Share on other sites More sharing options...

I'm going to the Ring in 3 days and need her to be in top shape! Quote Link to comment Share on other sites More sharing options...
davey_83 Posted May 8, 2017 Share Posted May 8, 2017 You will eff up the engine running if you do it wrong Quote Link to comment Share on other sites More sharing options...
Andymac183 Posted May 8, 2017 Author Share Posted May 8, 2017 You will eff up the engine running if you do it wrong In what way? This is my worry...! Quote Link to comment Share on other sites More sharing options...
Olly350z Posted May 8, 2017 Share Posted May 8, 2017 Id like to know what way as well... Quote Link to comment Share on other sites More sharing options...
Ekona Posted May 8, 2017 Share Posted May 8, 2017 No way to mess anything up doing the pedal dances, I think Davey was referring to the cleaning of the intake system. That's not something I'd be attempting before a Euro trip, rather I'd be putting up with high fuel usage and sorting when I got back. Worst case it's running rich, but unlikely to be to the point of bore wash. Quote Link to comment Share on other sites More sharing options...
AliveBoy Posted May 8, 2017 Share Posted May 8, 2017 If you get the pedal dance wrong, literally nothing happens, because you've done it wrong I'd make sure your air filter is nice and clean and maybe give it an oil change too. Quote Link to comment Share on other sites More sharing options...
Andymac183 Posted May 8, 2017 Author Share Posted May 8, 2017 She recently had an oil change...I'm gonna go dancing later today then Quote Link to comment Share on other sites More sharing options...
