Does your mfa work correctly? Do you get an mpg. If not then as prev mentioned itll be that.

Also check if the ecu has its vacuum line fitted. Ecu is under scuttle at driverside

there is also a vacuum line that goes to side of airbox to control the air direction flap, so that it sucks warm air off manifold on cold starts

Mfa works (apart from cracked screen!)
Shows around 35mpg but only achieving about 24 atm.

Vacuum pipe is connected to the airbox flap. Checked the vacuum which works ok but flap is a bit temperamental.

I'll check the vacuum pipe on ecu, is it in passenger footwell bit?
