Does computer shutdown fuel injector on misfire?

Asked by Nov 01, 2016 at 10:15 PM about the 2003 Buick Century Base

Question type: Maintenance & Repair

My son is at college driving a 2003 Buick Century. 85000 miles, second
owner (car was hand down gift from grandparents and always serviced),
intake gasket, all hoses, and water pump replaced last July. It ran rough for
two days and finally threw a misfire code in the #2 cylinder over the weekend.  
The car is definitely due for a tune up, never had one to my knowledge. It only
had 48000 miles on it when we got it 3 years ago. ASSUMING this is a bad
coil/spark plug issue, will the computer in this year model shutoff the fuel
injector in the misfiring cylinder? We're trying to get it back here to have the
problem addressed, but know it's bad for the catalytic converter to have that
fuel dump when it's misfiring. We've been told that some computers will shut
down the affected injector and wonder if we've got one of those model years.
He uses it for an 8 mile roundtrip to and from school and 30 mile round trips
to baseball practice.  Thanks!
