About two weeks. No odd behavior aside from the codes the first time. Started running like crap immediately the second. Still took two trips to the dealer to get it resolved after the second round of codes.
Also, mine could have been more extreme due to the fact that it was two injectors failing.

Just had the codes come back up today on a cold start after work. P0300 (Random/Multiple Cylinder Misfire) and P050D. Didn't notice it running bad though on the drive home and MPG's were the same as I always get. So odd. Wish it was able to tell you exactly what cylinders misfired.

If you get a OBDII reader (eg. bluetooth dongle and android torque app) you can see current and longer term counts of misfires on a per cylinder basis.

If you have a tune, I suspect it's unlikely your warranty applies. How would they know it's not the tune and why would they spend time they're not paid for trying to rule out the tune?

I have HPTuners so I think i'll hook that up and see what it says. It came on again today after cold starting it after work. Same codes. Light came on right as the RPM's started to drop to normal idle RPM's after the high idle from cold starting. Again I didn't notice any driving issues or MPG changes. I'm going to check all the wires and plugs to start with.

So i've scanned a cold start with hptuners and it's cylinder #7. It only misfires during the cold start sequence. As soon as that's done I don't get any. I drove around and went to redline and didn't get any. What would cause it to misfire only during the cold start sequence?

Old thread, I know. But you guys bumped it back in January, so I figured I'd air my $.02 in case any else comes across this in search:

CEL at 15k miles. Bone stock, so straight to dealer. Had same codes and they replaced an injector under warranty. At 19k miles now with no issue.

Glad it worked out for you.

Just to update my old thread, I'm at 102k miles now (yes, one hundred and two thousand), and haven't had any injector-related issues since 10k, or any other major problems actually.

Wow that has to be one of the highest mileage 6th gen camaros around haha.

I never updated this thread but I replaced my injectors also and it fixed the misfire issue also. Runs a lot smoother on cold start.
