This is not the same code as the first time. When I started my vehicle up to take it to get the codes pulled, and drove it there and back, it worked just fine. So hopefully the fix tomorrow at the dealer is quick! I have plans to keep.

When I had my first HHR, I had the "eng rdc pwr" thing pop up on my DIC, and the first time it was some sensor having to do with the throttle, dealer fixed it and it wasnt a week later it did the same thing again half way between Norwalk and Toledo.The second time they changed out the whole throttle body assembly and it was fine after that. It was a 1LT with the 2.2 and 5spd.

Could it be low battery voltage? That condition is likely to show up at this time of year. Try testing the battery, putting a charger on it and reducing electical loads when driving short trips. (The owner's manual warns of battery drain under some driving conditions - even with a good battery)

Mine was topping out at 30, barely accelerating enough to even safely get going. I was driving with my flashers on the whole time and in the right lane, hoping someone wouldn't rear end me because of my speed. I realized that I had done a lot of short trips with heater on, radio on, and battery-draining devices. I am a delivery driver at Jimmy John's, so I do a lot of stop-and-go, short driving trips that are probably hard on the battery. It didn't throw any codes on the computer when it happened to me. But I took it to O'Reilly and they tested my battery with their machine, and they told me it was still good. The "Eng Pwr Reduced" thing went away and cleared up on its own after charging the battery good. So Officer1151, on the brighter side, there's a chance it might just be too heavy of a load on the tiny little, barely adequate battery that we all have in our HHRs. At least that's what it was for me. When the time comes for me, I am going to get a little bit bigger, better battery to replace the old one. Good luck in solving your dilemma here!

Well here's the thing.. I had gone to start my car up, pending finishing a day of work. Turned it on, started and ran just finee. Heater was on medium medium high and speed was medium and flow was on the windshield. Headlights were off. Markers were on. A tiny led warning light was running. And it has 3/4 tank of fuel.

Sitting here at the dealership... Waiting for the verdict. I did see the code that the Tech pulled matched that I got from autozone last night. P2135. So it is indeed the APP sensors 1&2 not agreeing.
Will let you all know what the final word is.
