Hello everyone out there is chevy land!
I have recently acquired an 03' 1500 Avalanche z71, with a 5.3L V8 and It has been sitting for awhile. The engine only has 44,000 miles. It was misfiring and running lean codes on bank 2. I replaced the spark plugs, the wires, all 8 coils, all 8 injectors. It now runs quite well, but now it is pulling a single code p0308 (cylinder 8 misfire). I have swapped coils to see if it was a bad coil, no luck. What else can I possibly do to try and resolve this? The injectors are AC Delco injectors, the rest is autozone parts. I am lost here, as this is my first chevy.
I also noticed the check engine light generally comes on when revving to medium RPMs, it will flash, and then turn off after while idling. If left idling for about 10+ minutes, the check engine will come on and stay on until I reset it with my meter.
Please help oh great chevy wizards!
