I know this is a sore spot with a Nissan, but I do own two
GM cars and a Ford trk, but just happen to own a 2003
Nissan sentra XE. It's been a good car but has been missing.
Parts store said #3 cyl had misfire. I changed the wire and
sparkplug with no change. This car will run perfect at times
and other times it will miss. Head gasket was replaced not long
ago. Can a coil or injector act up like this? Hate to spend big bucks
tracking down a miss in a 10 yr old car. Mileage is 150.000 and
ck engine light on.
