If you ever get new injector and you want to throw these old ones away could you please courier 1 to me? Need to see how they fit on the alfa head design. The original 3.2 injectors for my alfa probably wont flow as much as the 3.6 injectors and i might need extra flow for future forced induction.

Yes i know but the alfa has smaller injectors than the camaro. The hpfp is the same as the camaros though thats why i just need to see if the camaro injectors fit.

I've removed and replaced the injectors on a LLT. It's difficult due to the clearance between the heads. There is a very specific sequence outlined in the GM Service Manual. I had to follow it closely, otherwise you can't remove the fuel rails or the injectors.
Get a hold of the book. BTW the engine I was working on was out of the car. In the car will be even more difficult. Pay attention to the high pressure lines and the fuel regulator connection on the back of the block. Good luck, Rich

Can anyone provide some recommendations? I might have faulty injectors on my 2010 Camaro V6...

Issue:
During idle and driving I maintain around 18% on both bank 1 and 2 long term fuel trims, 0 to 3% on both bank 1 and 2 short term fuel trim, both upstream O2 sensors oscillate between 0.1 to 0.9V, fuel pressure stays between 40 psi to 75 psi. One think I did notice the long term fuel trim actually going up to 21% or a little higher on both banks while driving. Any help would be greatly appreciated!!!

I'm on my stock chains, 101k miles. Cammed as well!

My misfires were VVT Solenoids.


Any time you replace:
Spark plugs
Coil Packs
VVT Soleniods
Fuel Injectors
CAM Sensors
Intake

Pull fuse #5 and #20, and wait. Then plug them back in and do the idle relearn.

Mine ran phenomenal after doing so.

ECU was using learned values as parts wear, on NEW parts, so resetting the
Keep Alive Memory took care of all that.

The VVT solenoids are pulse width modulated, and they have a resistance to their
coils. Well, replacing them with new ones, will change the movement of the new
VVTs. Being new, they may open too far, or not enough. The OEM VVTs were
around 8-ohms, the new ones were as high as 10. So, they were not being
controlled effectively. So, resetting it all, drastically changed the performance
of the car. I thought it just did not like the new VVTs, but it was the parameters
the ECU was using. It has to be reset.

I dealt with this issue last week. i have a 2010 RS with 99800 miles (no mods), original owner. my check engine light came on at slow speeds, lost power, white smoke came out of the rear mufflers.

i have a friend who is a chevy mechanic at a local dealer. he scanned the vehicle (obd2) and told me injector #5 was bad. he recommended i replace all 6 injectors, 2 small metal fuel lines and a new gasket for the manifold plate cover.

i didnt keep any injectors. i trashed them

car runs great. all new parts are GM products.

Cease
