Default CVH EFI powered Westfield
Hello
Can anybody help me?
I have just converted my CVH powered Westfield SE from Carburettor to EFI, due to strict German environmental laws. Basically I have taken the complete engine, loom and control system from a donor XR2i car. Everything is now installed into position and the engine is running, however it is running very rich (CO2 = 2.3%) with all sensors connected. When I unplug the lambda sensor the engine runs better (in emergency limp home mode I guess). I have ordered a new Lambda Sensor but that will take a week or so to arrive.
Does anybody know if a faulty lambda sensor would command more fuel than the emergency mode?
Additionally I have a standard westfield Exhaust manifold fitted Which is a 4-2-1 set up therefore I have had to position the lambda sensor further away from the engine than the original fiesta set up.
Can the position of the lambda sensor also affect its efficiency?
Could the Map sensor also be responsible for the engine running to rich?
Any advice would be appreciated.
Cheers
Paul
