1.8 zetec

[mk1fiesta]

hello everyone
my engine is a 1.8 zetec with standard intake manifold the engine starts after
three attemps and then runs ok apart from a slight hunting idle also i have white smoke
from exhaust with smell of petrol and my oil smells of petrol i have attached my msq and a data log
im hoping some one can have a look at them and see if all the settings
are as they should be thank you

This usually means you are running a bit rich, but the data log doesn't look that way. Make sure your exhaust doesn't have any leaks that are letting in outside air. Where is your sensor located?

hi
matt thanks for the reply
i have checked my exhaust it does not seem to have any leaks its got a brand
new manifold gasket and new manifold to downpipe gasket
my lamda sensor is located in the exhaust manifold downpipe just
before the connection to exhaust

Exactly what sort of O2 sensor and controller are you using?

matt thanks for the reply
i am using a 14point7 spartan 2 controller
and a bosch lsu 4.9 wideband 02 sensor

I'd make sure there isn't any leaks in the exhaust then.
