Hi I have finally finished my bob Robin no just some getting troubles.

I seem to be doing around 15mpg and it can't hold it's idle only when hot.

I think it's running rich,... I checked the plugs they are dry and black sooty is this about right?

I have new O2 sensors only those 3 wire universal cheap ones on eBay (15) each. Hope they are good enough?

I have checked cleaned icv act and ect.

Now the only thing I am using is a boa ecu but a bob maf are the 2 sensors different? I think a couple guys on here have done a boa conversion and was wondering if I can have a part number for one that's on the maf sensor casing. This it the only thing that must be causing it.

Dry and black - yes, rich...very rich....
