Fueling issues LLT
Hey guys, I have a 2011 LS with the LLT and have been having fueling issues for a bit. A couple months ago, after a road trip, I went and got a car wash and at the end the Camaro started running extremely rough with a CEL, thick white smoke, ‘Reduced Engine Power’ and fuel was literally spilling out of the exhaust tips on both sides. Gave me these codes: P0306, P0303, P0087, P0089. I went ahead and swapped all 6 injectors and the fuel pressure sensor. Turned out one of the injectors from cylinder 1 wasn’t working, confirmed by swapping back’n’forth. So I closed it up with 5 new injectors and 1 old working one. Yesterday I did a really hard pull and the exhaust started popping like crazy on decel. CEL, white smoke, and reduced power came up again. This time it only showed codes: P0300, 0301, P0087, P0089. I dropped a new injector in and it runs much better, but it will keep dropping a CEL with just the P0301 code and doesn’t run AS smoothly as it should. It also has a heavy fuel smell. I swapped spark plugs between Cylinder 1 and 3, but it still is showing P0301. Not sure what to do now, so any suggestions?

Number 1 plug wasn’t ever wet, but I looked down into the cylinder and could see the piston was saturated.
