Question about 2007 Chevrolet HHR Special Edition
Hard shfiting i changed out the Air flow sensor and new air filter
Did you get codes from the PCM? You did not say the check engine light was on.
If the Tracation Control light is coming on, the tracation control is activating and can cause a jerking problem. Nothing last the life of the vehicle, however the timing chain should not need to be changed at 49,000 miles. If it does, I would have them do it under warranty. See if you can get the codes and send them to me. That way we can get a better ideal of what is going on. Could you please tell me what these codes stand for?
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day

The MAF (Mass Air Flow) sensor is a very common problem with these along with the pickups. This isn't what you would call an inexpensive part. Definitely do some shopping before you buy one.

Yes. That is exactly it. The Air Intake Temp Sensor is built into the Mass Air Flow Sensor on the Air Filter Box. Below is a picture...
I personally have not connected one of these Chips to a Tahoe...What I can provide you with, is the Connector Diagram so you know exactly what Wires you need to Splice in to. See below...
I hope this helps you. If you have any more questions or need any more diagrams, please don't hesisitate to ask...Thanks again, JShreader.

It's should be a simple remove and replace. Just make sure the engine is off. Also do not touch any of the filament wires on the sensor, just the plastic housing. Also after you install it drive the car for a little while (city speeds, cruising speeds and inbetween). That way the computer will be able to readjust its setting since it is a new sensor.

Check any vacuum hoses from engine all the way to heater/a/c housing under dash,for leaks. Then manually move or put a vacuum guage on every vac motor you can see and get to. Your working your way back to the switch. If you want to you could start at the switch but % wise and degree of difficult your better to back in. Now a schematic will make the process easier. Hard to work on a system you don't know .Electrical or Computer sometimes play into these, I have an older S10 so no computer.
