Get the hotter plugs it will clear the problem.
Make sure though the dealer makes the change to the ECM programming to take into account the hotter 2008 plugs in a 2007 GXP.

Got my car back after the fourth time to the dealership!
Diagnosis-Check engine light on misfire on number 4 cylinder. Bad injector. Have to replace all four injectors, high pressure fuel pipe and intake gasket due to removal to access injectors and replace. Test drove. No check engine light or misfire.
My Check Engine light came on my 2006 Soly noting it has 7234 miles on it. I aske a mechanic and he said it is probably my gas cap. I tightened the cap and the light is still on. I then went to the Autozone store to get a "reading" from the ECM. They noted it was code PO833, a clutch pedal switch "B" malfunction.
Has anyone had to replace that item? If so what was the extent of the repairs?
Hello I am new and having problems with my engine light. The code reader (ala Harbourside Freight) says Timing but the car runs great and it's an emissions light per the manual. Any thoughts before I spend a fortune bigger than my car at GM?
Had the same problem with my wife's car (07 Pontiac Torrent). Try a new (from Pontiac) gas cap. The one from Auto Zone didn't do a thing.That is usually the problem.
Your concern is certainly understandable. Keep us updated. Feel free to contact us if it isn't being addressed properly. I hope the problem is fixed quickly for you.

I'm having this same problem with my car. Did they replace the injectors with the same part/injector or did they install some type of new designed injectors? Seem stupid to install same defective part again if it failed the first time, why would the same part not do it again later? Anyone know if this is covered as a defective part and gm pays for it or do I have to pay out of pocket?

the injectors like most mechanical parts wear out over time. Some wear out earlier than others. There could have been some contamination in the fuel that caused one or more injector to wear prematurely. There could be particulate matter that comes adrift from the HP fuel pump, there are a lot of ways that injectors can fail. That does not mean that there is anything wrong with the design of the part.
The cost of building parts that are very highly reliable goes up exponentially with the failure criteria. Our HP fuel pump failed at 23k miles. I was perfectly happy to have it replaced with the same part number. It will most likely go for 100k miles without any issues.
