K simple thing first, check engine light comes on and off when ever it pleases I'll start it one day and it will be on but then I start it 2hours for last start and it's off or even a couple minutes away from each one... Help cause I have payed that away thinking it something stupid but now not so sure
Second she seems to be making weird noises such as when I'm driving and I step on the gas in makes a low pitch whine but I'm thinking that's the injectors? And also yesterday and today it sounded like she back fired in the engine bay? Looked around saw no leaks or oil coming out of the head or valve cover, and oil levels are fine. If you have advice that would be great!
