hi all, my wife uses the zed mostly for going to & from work, its about 15 miles a day in total. when i get in it at the weekend, i like to have a little play, but as soon as i floor it it chucks out a big cloud of grey smoke, it does clear and gets better each time, its done 68,000 miles and had recon tubs at about 60,000. im thinking 02 sensors or just choked up from the misses pottering around, any help or advice would be great, dont like it being driven if theres as poss problem.

thanks steve

Hi,

 

It could be a sensor playing up .. ECU sensor, water temp sensor .. If they were dodgy then the ECU would compensate by over fueling I guess.

 

Best thing is to get it on a conzult and replicate the problem and read the results.

 

Sorry I couldn't be more help.

thanks for that, does it have to be a conzult? i have access to a snap-on scanner & an E.G.A (gas analiser) would an emission test show anything do you think? i noticed the tail pipes are both black & sooted up, so its looking like over fueling.
