hi guys iv got a 2005 fiesta st and its doing my head in . the abs & handbrake light is on all the time & the mileage display flashes eac fail .
iv changed a throttle pedal & still the same . iv tried 2 throttle bodies still the same ? any ideas guys ? iv put it on a snap on diagnostic and got the following fault codes . u1900 , p0403 egr related but car has not got one , p0073 ambient air temp sensor circuit high (cant seem to find a air temp sensor) . iv changed the plugs aswell but its abit lumpy slight misfire on idle .
