Misfiring?
I have a 2013 Acadia SLT that at random
times while already driving starts to idol
past 3, a bell sounds, RPM needle starts
going haywire, engine light comes on,
stabilitrak and all wheel drive needs
servicing, and the doors sound like they
keep locking. Brought to dealer several
times and they cannot figure out what the
problem is. Any ideas?
