i know this is a common thread so i apologize,

 

my new zed runs rich and im trying to work out why, she has a good idle and no black smoke, however she smells of fuel and the exhausts sooty.

 

i know obvious ones like boost/ vacuum leak but the id say the gauge reads about right.

 

she ran low on fuel the other day but she was running rich before that, not sure what else to try,

 

she's going to zedworld for a cambelt/ service at the end of the month, just wondering if anyones got any suggestions until then?

O2 sensors lazy or dead, can afffect the fuelling. Jeff can put it on conzult and confirm for you when you are there. You can try disconnecting the O2 sensors to see if it makes a difference in the fuelling. Disconnecting them will revert the ECU to a means setting for the O2 sensors, mine has been running with out for the last year or so.

The temp sensor and the maf can also affect the fuelling, clean the connectors and check for corrosion on the terminals.

thanks ill try that.
