Hi Guys,

Can anyone help.

I have a 2005 Punto 1.2.

Car has just come out of an MOT test and the engine managment light is on.

Its come up with 2 fault codes.

P0170 - Fuel Trim
U1600 - Undefined code

When the car is cold it struggles to start and runs a bit rough with a missfire , and when she is running the exhaust gasses stink!!


Many thanks

Adrian

fuel trim i would assume maybe either lambda sensor, air leak / air sensor fault, maybe a fuse problem/wiring, just a check of all the usual basics is always good, such as spark plugs and the like, the other code i think has something to do with the immobiliser / CAN system
