Trouble codes
Ok so I have a 2002 Dodge ram 1500 slt 4.7 2wd, now before I get to the codes I'll layout what I've done to the truck since October. I pulled the motor and rebuilt it from the crank up, it has rebuilt heads all new gaskets, new timing components, new water pump, belt tensioner, thermostat, alt, battery, clutch fan, harmonic balancer, cam and crank sensors, throttle and idle sensors, new intake, etc so when I bought this truck the motor was locked up I yanked it out tore it apart rebuilt and replaced any part that was not in good shape. The pcm was bad so I went to the junk yard and pulled one from a Dakota swapped the tone rings to match this pcm. I flashed it to my vin and I've gotten about 4,500 miles on it since October. Well last week I could smell coolant so I popped the hood and I had a leak from the water pump so I went ahead and pulled everything to the timing cover replaced every seal and gasket , put a new water pump and clutch fan, thermostat etc.. started it up it drove fine but then yesterday I came home from work and when I parked it I had no DTC but this morning I started it and it sounded week starting. So I fill it up come back and I put my code reader on it and I get 6 DTCs I clear it drove it and didn't come back restart it and Bam I've got more codes. I'll list them at the bottom any thoughts or suggestions would be appreciated.
P0300,p0301,p0304
p0600,p0603,p0072
So I've got cylinder 1,4 misfire
Multiple cylinder misfire these were the first codes.
Keep alive memory
Serial communication link failure
Ambient air temp sensor circuit low these came on the second time but they have only came on once

Ok cleared it out and so far no codes, I did notice it started easier but I'll let you know how it does after I drive it.

Ok so I drove it yesterday no problems, but this morning when it was cold I had a hard time getting it started, it popped back a little almost like timing but I just did the timing in October, very hard start but once it got started it was fine, until I took my kids to school when I was accelerating it was surging for a little bit then quit. Low RPM in drive at stop it's like 500rpm. So I know some vehicles don't like aftermarket parts so I'm wondering if my TPS might be the issue. The only aftermarket parts I have are TPS, IAC and I think the camshaft sensor might be aftermarket. No codes of any kind, live data looks fine.
