2006 Problem Child
I love my HHR she has ran awesome in the 3 years i have had her. Now as she crosses the 100k mark we get problems. We couldnt get our code reader to give us the same code more than once so took it to the dealership and we started of with either "injector or ignition module". (my husband called the tech an idiot at this point) :)
They changed the first injector, engine light went off for 18 hours, took it back they thought a second injector went out. Seemed legit. My Father in law was a Chevy mechanic for 20 years he agreed.
2nd injector changed, light back on 24 hours later. took it back, deemed they had a slightly different part and got a matching injector back in it, plus changed the ignition module too. *(all under warranty thankfully)
Car was good for a day, engine light back on, the light was intermitten all weekend and then finally right before taking it back the engine started dying. they could not figure it out at (Hyndai/Kia dealership where purchased and warranty) so they sent it to the local Chevy dealer to have codes read. They were at a loss and could only figure out that the timing has now jumped.
How is this possible? Anyone else have similar issues? Need some advice!

Timing jump is possible, mostly from worn out timing chain & guides.
There is a TSB about replacing injectors with the "new improved" injectors, the don't mix and the ECM needs reprograming.
You never did state any of the codes. It is not unusual to have different P030x codes. The P0300 means random mis fires, P301 means mis fire cyl #1 etc..
If you have an after-market warranty, you can take it to any shop you want to usually. Read your contract to make sure.

Welcome to the site 
here is the tsb for the injectors. If the dealer change one or two injectors with the new type then it may not be possible to get the car running properly until the others are changed and the reprogramming of the PCM is compete.
#08-06-04-001B: Check Engine Light On, DTCs P0171, P0300, P1174 Set (Perform Injector Test, Replace Injectors and Reprogram ECM, If Necessary) - (Apr 21, 2009)
Subject: Check Engine Light On, DTCs P0171, P0300, P1174 Set (Perform Injector Test, Replace Injectors and Reprogram ECM, if Necessary)
Models: 2006-2007 Chevrolet Cobalt, HHR
2006 Pontiac Pursuit (Canada)
2007 Pontiac G5, G6
2006-2007 Saturn ION
with 2.4L Engine (VIN B, P - RPO LE5)
Condition
Some customers may comment on the check engine light being illuminated.
A scan tool may reveal DTC P0171, P0300 or P1174 set as current or in history.
Cause
This condition may be caused by the plugging of one or more of the injector director plate orifices which results in a lean condition.
Correction
Important: This condition cannot be corrected by cleaning the injector(s).
Important: For Chevrolet and Pontiac vehicles, reprogramming must be done using the remote method.
For Saturn vehicles, reprogramming must be done using the pass-through method.
Follow the published diagnostics in SI for any DTC recorded.
Perform an injector balance test using the Active Fuel Injector Tester (AFIT), CH-47976. Refer to the Fuel Injector Diagnosis (w/CH47976) procedure in SI. If any injector is identified as having a lean condition, replace all four injectors with the revised injectors. After installing the new injectors, reprogram the ECM with updated calibration files using the TIS2WEB Service Programming System (SPS) application. There are two calibration part numbers that are valid for "Engine Operation". Select the part number with the description that reads for vehicles with second design injector. The injector has a dark blue overmold color for this repair.
Important: The fuel injectors must be replaced and the new calibration files must be installed to ensure a complete repair. Failure to perform both repairs will result in the customer returning with the same condition.
If a vehicle returns with the same condition after having this repair performed, the technician should first verify that the complete repair was performed before continuing with SI diagnostics.
