Filled up with gas yesterday and today my engine started missing especially when under heavy acceleration.Could it be bad gas or is it something more serious?
Engine missing on 2008 Chevrolet Equinox
It could be the gas - or something more serious. If the engine in your 2008 Chevrolet Equinox is running that poorly the service engine soon light should be on and fault codes will be set in the engine control module. Reading and diagnosing the fault stored fault codes will help determine the severity of your problem. If your service engine soon light is on please read the repairpal blog regarding the "check engine" light and what it means. Here is the link: http://repairpal.com/check-engine-light. (The "check engine light" is the same meaning as the "service engine soon" light.)
It's not the gas, the engine misses. My best guess is that it's due to factory engineering because it's done it since day 1.
