2010 Hyundai Accent Cylinder Misfire
Cylinders 2 and 4 started misfiring in my Hyundai
Accent. All spark plugs have been changed, all
coils have been changed and the fuel injection
system has been cleaned. A leak in the gasket has
been fixed as well. My car is still misfiring. The
dealer I went to suspects an ECU problem. My
mechanic friend wants to put a new O2 sensor in
and reset the computer to see what happens. What
do y'all think?
