Please help and thank you in advance. 2012 camaro ls with only CAI mod. While driving car on freeway there was a sudden decrease in power and engine was louder than normal. The check engine light was on and stayed on consistently without blinking. I made it home but it felt like a struggle. We just changed out spark plugs and air filter. The check engine light has disappeared and after running the basic scanner, came back with codes $7EA, $7EB, $7E8: Engine which doesn’t help. The engine is running louder than normal and the engine bay smells of gas. I haven’t taken it out for a ride yet, I don’t want to get stuck on the hills here.

Leaky fuel rail, its either that or a injector gone bad

Has the engine started to rock and roll? I have the manuals (Factory) for the car and everything you describe even limited by your meter. Points to the fuel rail leak caused by injector either offline, causing the smell. I am sure the rest of the codes are related to the rail.

It turned out to be the catalytic converter.
