Hello folks,
I'm wondering if anyone else has heard spark knock on their 4 cyl. Terrain or 'nox. Mine started at about 3,000 miles (now @ 4,000) and progressively got worse until it was bad enough to where the dealer could hear it (first trip to the dealer ended up no problem found). This is the first Equinox they've had with this problem, so they called GM for diagnostic help. GM tells them to perform a top end engine cleaning and recommend top tier gas only for this vehicle.
Well, my first thought was what a load of crap. But after the cleaning, the spark knock is gone... for now. I'm concerned about the long term issue of dealing with this. Has anyone else had any similar issues?
Quite frankly, I'm not too keen on having to search for top tier gas stations anytime I need fuel.
