Engine light...

Keep getting PO170: Fuel Trim Malfunction (Bank 1)

any ideas what this actually means?
always the first time i put my foot down then lift off after accellorating up slip-road on to the A3 in the mornings...

getting annoying now, car is running fine (except cooling issues)...

any idea what that code specifically referes to? injectors? or mapping? or overrun?

just want to know what i need to do to sort it out...

thanks
Oz.

thanks, sounds like i will have to live with that then...

i have an emerald ECU doing the fueling, so chances are its putting in more fuel than the stock ecu would allow and throwing the error code, even though the A/F is perfect ratio, and the car is running flawlessly...

annoying...
