Hello forum,
I had a bad intake valve on bank two and had p0171, 174, very large short and long fuel trims, after driving a bit with engine losing power, so I replaced both heads with rebuilt heads purchased off Clearwater Cylinder Heads, also timing belt/pump, spark plugs, injectors, front catalytic converters and minor items. I keep getting multiple misfires on both sides on start. There is also a some noise from either valves or injectors and very noisy engine. I've double checked the timing belt, removed everything up to the new heads and inspected. It seems everything is aligned (dots on cams, crankshaft, timing marks). The camps are torqued to spec and turn, and engine turns as well. Where do I start diagnosing the issue? So far multiple days spent and I am pretty upset looking at the possibility of engine replacement now.
