Sooo dealer says code shows misfires on 5 cylinders and ISTA shows ignition coils need replacing. Wanted $1,100+ to replace coils and plugs.
I can get the parts for about 400 bucks and will do this myself.
They said it's not unusual to need coils after only 57,000 miles, and that the factory Bosch coils are now replaced with Delphi, which last longer.
Coils in my 97 328 at 235,000 miles have never been replaced...
