HHR ss
I have an 08 as recently have had power loss and gas mileage loss has auto trans when in low end of what I guess is overdrive and u accelerate it has a biggish vibration and poor exeleration turbo boost fine maybe more than normal and extremely worse if ac is on while idling has somewhat of a miss and don't through any codes started maybe a month ago and has gotten worse starts doing it around fifty and stops a little over sixty but even in passing gear take off is poor to what it use to be any ideas

That looks like it should have been 6 sentences. Probably done with your phone and voice.
Anyway, if your SS is stock, you should hit about 14 PSI of boost when you really get on it. If you're getting that, but the power is not getting applied to the wheels, I might suspect you have an automatic transmission that is malfunctioning.

If anybody has any idea's please let me no I had a check engine light come on and auto zone said it was my thermostat and auto repair shop said if it wasn't opening and closing like it should that it would cause power lag

Please keep on track with one thread, I've merged this into the mix to avoid confusion.
If the code was P0128, they would be correct, please only use an AC Delco OEM thermostat, and Dexcool. The computer doesn't like the green stuff!!
And yes it will cause the condition you described.

I'm not understanding how a faulty thermostat causes any lag. Since it's ecm related I'll assume that it tries not to overheat by limiting power. Our SS, before the swap, pulled 12-14lbs of boost while hitting temps near 250* it had timing and head gasket issues to begin with and a few CELs. I don't think I had 0128 though (can't remember). Had plenty of power for the test drive though. The old motor only stayed in for 500 miles before we tore into it, 350 of that was the drive home.
Another source of my confusion is the SS having good days and bad days? Was there a CEL on both good and bad days? How many miles on that SS Cody?
Most importantly, WELCOME to the site!
