Why are coils burning out? on 2005 Scion xB

After having air filter changed, car stared running rough. Check engine lights all on. Sputtering noise from tailpipe and does not accelerate well at all. Dealer said it was fuel injectors and changed them, but didn't get out of parking lot before lights came back on. Had 3 coils changed since then. Runs a week or two and same problem starts. It has 160,000 miles on it. Is it a short? Bad coils? Spark plugs? Or time to get rid of this car that I really do love? Any help is greatly appreciated!

did you have coils changed by dealer or were they aftermarket?
