I have the same problem as the author of this post.

My 2011 V6 1LTE Camaro with 80k miles started from nothing to have road trouble on January 1st of this year. Multiple P0300 misfires, a strong gasoline smell and the intermittent CEL. My scanner that I always have on hand, I got P0300, P0089 bad fuel regulator. Misfires in cyl 1, cyl 3 and later cyl 5. The next day it started after several attempts and seemed to be running half normal, unlike the engine feels heavier than normal and fuel consumption shot up to almost DOUBLE

Then a few days ago the car began to have the same fault, unlike now I got the P0087 (low fuel pressure) and reduced engine power.

I changed the high pressure pump did not solve.

Then I changed the injectors for a NEW AC DELCO, and now the car runs normal again. The engine still feels heavy and consumption is still high, I think it is because of the fault catalyst. I didnt use the car anymore, I have it parked until I see what I can do with it

You dug up an old thread posting for help.

If you had started your own thread you may have got an answer.

Most of the time these old threads get dug up by spam bots.

@moloko let us know if you fully solve the issue. Seems like these misfire issues are common on LLT engines at higher mileage.
