hey last night i plugged my programmer in to show my trouble codes and a p0611 showed up, when i got home i did some research on the forum and somebody had the same issue was told to install stock tune and see if it goes away, i did that and it went away... i let it idle for about 5 minutes and still didnt come up. i installed my eco tune back on and checked for troubles and still didnt show up. so i took it around the block and held it at wot a couple times and when i got home i checked for codes again and this is what i got p0264, p0267, p0273, and p0282. those are cylinders 2, 3, 5, and 8 injector circuit low codes... im guess i should replace my ficm????
