P0134 issues

[Shawn1974]

This issue is baffling me. I'm getting a p0134 message. I've replaced both of my oxygen sensors. I've replaced both of my PCV valves. I've replaced my mass air flow sensor. I replaced my coil pack and my spark plugs. My O2 sensor is pegged out at 1.25 volts but my other O2 sensor has reading . I've uploaded my data if anyone can help me on this I would appreciate it highly . Thank you

Had similar issues last year. Ended up being my timing chain. Replaced in July. $3k later. It purrs like a kitten. Replaced similar parts as well. Finally gave up and took it to the dealership. Knew it was gonna cost me. Plan on driving my sonic for many years to come. Sorry for your luck.
