Hi, i have a 04 vz calais and in the last 3 months have been having a world of problems.
Just after some opinions.
The car started misfiring so i took it to the mechanic and he done a major service, serviced injectors, replaced vaccum hose and oil pressure switch, the car was fine for a few weeks and started missing again with a lack of acceleration so back to the mechanics he has diagnosed it and a fault with injector #4 so that got replaced but the car still had slow acceleration it just has hardly any power won't go past 40km/h he has diagnosed and has said that lots of codes have come up injector 4, coil 4 and a few others he is thinking that the ECU is faulty and needs replacing and that's why it keeps throwing so many different codes
Any thoughts?
