I want to know if anyone can verify that this is the right part #(217-2907) for an 07' 2.4 LT............

That number crosses over to GM part number 12606110 which is the injector number for the '07 2.4 LE5 engine. I think the number you have is the number that AC Delco assigns to them so you should be good to go. If you really need to be 110% sure just ask ChevyMGR, he's the man.

Yeah, I looked around and got the same GM part #. I'm pretty sure I got what I was looking for now...............

Just a question on injectors, if you replace one or all do have to have you ecm programed? I really do not think so if there oem spec but not sure... anyone replaced there injector and not reprogram the ecm? Thanks

There is no reprogramming required when replacing injectors. How ever it's always a good idea to reset the adaptive memory in the PCM when installing new injectors. This can be done by disconnecting the battery for 5 min. The system will relearn without resetting the PCM but will take some runtime to do so.

Just a quick note on injectors, I was taught to replace them in complete sets. The reason being that over time and accumulated mileage, injectors lose some of their performance. Like any mechanical part, they are subject to wear.

Thanks for all reply's ,i will replace all of them but i keep reading about the dealers reprogramming them with a update..

Ok you Jared my memory. There is an updated part number injector and for the updated part number there is a reflash that needs to be done.

Here is the tsb on that see if it matches your car

#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.
