2011 silverado
So I have a 2011 silverado it now has 120,000 on it
i have had this problem goin on with my truck for
about 3 years off and on it started when I had
reached about 75,000 miles these lights would
come on service stabilizer track/service traction
control/ and something about the ecm/ than it
would say engine power reduced and would ride
very rough and when it shifted it shifted pretty hard
and sometimes the truck would just shut off when
I'm driving. Can someone one plz help me figure
out what it is? I took it to a mechanic and said it
was a cylinder 6 missfire and the o2 sen but I
changed that and didn't do anything.
