I have a 05 Pt cruiser turbo, it runs like crap and will not throw any codes. It has something to do with the number 2 & 3 injectors. I have replaced them and still no change. However when I go in with a scan tool and command either of the two off the misfire gets better, I can smell gas so I'm pretty sure they are being commanded to stay open. Other than the pcm being bad I have run out of ideas.
