I have been positing in my build thread, but might need some help here. Build Thread
So I replaced the motor in my 99 Suburban K2500. 7.4 Vortec. Everything is stock. I took the motor from a parts truck, and replaced all the seals/gaskets etc.
During the install I had the distrubutor 180 out. Got that fixed, but now I'm plagued with a misfire, and occasionally a P1345(cam crank offset code). I have pulled the distributor out multiple times, and I'm 99% sure it's in exactly like it's supposed to be. It idles fine, but I get a miss at around 2k RPM under no load, and miscellaneously under load at multiple RPM ranges.
Along with the P1345 I have
P0140 - EGR
P0137 - O2 Sensor
P0154 - O2 Sensor
EGR Valve is new, I do have an exhaust leak from where I cut the exhaust out. I put a flex pipe on for now, but it's not a good seal. I am not sure if that would cause the EGR code, but I'm sure that could cause the O2 sensor codes.
Without more codes for the misfire, what can I do to get this ironed out? I would love to have it all back to perfect.
New items are:
Injectors
FPR
Spark Plugs(gapped to .045)
Cap/Rotor
Plug Wires
Oil Pump
Gaskets/seals
The only thing that wasn't installed on the old motor were the plug wires, and it ran fine then(besides the rod knock, but no codes).
Is it possible that I still messed up the distributor install? I watched probably 10 different videos, and read more write ups than I can count. They all had the same info, and I followed that to a T. Rotor pointed towards the "8" arrow after being fully installed with #1 cylinder at TDC compression stroke.
Any help is appreciated
