I've had my 2012 Enclave for 2 years. Two months after we bought it, white/gray smoke that smelled like gas came from the exhaust. Lights came on and the engine lost power. The code indicated a specific misfire. Replaced that coil pack and plug. Issue solved. I did end up with a complete tune-up about a month later. Now it is doing the same thing.
Just after Christmas, I drove it to my destination. When I tried to leave, it wouldn't crank. Acted like it wasn't getting gas. It tried to start, but wouldn't completely turn over. After 2 days, it cranked fine. Then a month later, it started with the smoke and gas smell again and loss of power.
The engine codes don't really help - P2228C & P0300. No specific location. The smoke is not oil or antifreeze. (I change the oil every 6K miles with full synthetic.) I don't want to keep doing tune-ups. That's just a bandaid. The threads indicate either a coil pack or fuel injector. Don't want to spend 100s of dollars on something that "might" work. Please help! Thanks.
