I have a 09 Pontiac G8 3.6l with 227,000 miles that recently started throwing a misfire code for cylinders 1,3,5 and the scanner at autozone says bad injectors but I doubt that since i’ve never replaced a single injector in anything i’ve owned. I started with the maf sensor which wasn’t the problem, then went with the cam sensor but I didn’t put on because I leaned towards injectors, should I replace the injectors or what? I’m really lost at this point and can’t find anything on what might be my problem. It’s not all the time but when it does happen the car shakes at low acceleration and when i floor it, it goes away. any advice?
