I’m selling my 2010 Equinox. The price reflects the fact that it needs a repair: the engine starts fine, but the check engine light comes on after 10 minutes. It has new spark plugs, a new timing chain, a new head gasket, and a new alternator. I was advised to replace the engine control module (ECM), but I don't want to invest any more money in it. Is anyone interested? The vehicle is free of rust; it arrived in Wisconsin in March 2024.
