Fiesta ST Stage 3
Not to sure what this is . Im running the old mans car / my old one till get something soon and the idle is realy rough and not smoth if that makes sence some times sounds like its going to die but never does and drives spot on just this idle that does not sound right ??? The car has been run on 95 ron for the last couple of weeks and just had a new coil pack and lambda sensor. Does the lambda sensor need a few miles to work right ???
Any help would be great
