got an alfa romeo 156 gta
bought a few weeks ago.. zero issues until I serviced it
Did a full service and changed the spark plugs now I have misfires on cylinders 3 and 4 though was fine once done these have appeared soon after. can you test components or do I have to move coilpacks plugs around and see if the misfire moves as well
Also after brake fluid change the car reports abs failure though shows zero fault codes speedo now hoovers around the 300mph mark and it kicks my out every time i try to get readings from the wheel sensors any ideas please
