TRY swapping back to your factory coils. I believe you are gonna find these coils are not compatable with the gm system. I assume truck is running fine? also the plugs may not work well with truck but this would show a po300. computer is designed to be able to tell the resistance in the coils and the amount of enegy used. when you swap with different components it messes with the values it expects to see. helped a corvette owner with similiar issues here:

My 2001 dodge Dakota is running rough and the check engine light is on.


You'll have to look up the actual procedure to test the coil for code 351. The code means the computer is not able to fire the coil on demand which could be caused by several things, including a faulty computer. It could also be a problem with the wiring between the coil and the computer.

From a reputable repair website:


P0351 - OBD-II Trouble Code

Auto Systems and Repair

Ignition Coil "A" Circuit Primary/Secondary Malfunction Our emissions expert has put together the following information about the P0351 fault code. We have also included diagnostic procedures you can take to your repair shop if the mechanic is having difficulty analyzing the code.
OBD II Fault Code
  • OBD II P0351 Ignition Coil "A" Circuit Primary/Secondary Malfunction
What does this mean? The ignition coil or coils are responsible for igniting the air/fuel mixture inside the combustion chambers. Without reliable performance from the ignition coil(s) the vehicle will stumble and misfire.
Code P0351 indicates there's an electrical problem in either the primary ( the computer side ) or the secondary ( the spark plug side ) of the Ignition Coil "A" Circuit.
Symptoms
  • Check Engine Light will illuminate
  • Engine idles rough
  • Engine misfires on acceleration
  • In rare cases, the engine may not exhibit noticeable symptoms
Common Problems That Trigger the P0351 Code
  • Defective Ignition Coil(s)
  • Defective Spark Plug(s)
  • Intake Manifold Vacuum leaks
  • Carbon buildup in the Throttle Body air passages
  • Defective Idle Air Control Valve or Electronic Body
Common Misdiagnosis

DTC Reported P0505,P0351 What does this mean?


google it or better get the FSM for your car, and read how to do the tests, that prove what causes each DTC.
505 idle speed failure.
351
http://www.obd-codes.com/p0351

there are 5 engines, so first find that out,.
351
ignition Coil # 1 Primary Circuit Peak primary circuit current not achieved with maximum dwell time.
this means the coil primary is open (other books show the fail is for too low current (open coil in COP)

505
Engine started; system voltage over 11.5v and the PCM detected an unexpected voltage condition on one or more of the IAC motor circuits for 2.75 seconds with the IAC motor active.

id fix the 351, cop coil , its probably bad, or bad connections to it.
then clean the iSC,
then reset all codes, with a scan tool
drive 20 miles or until CEL glows, driving and the rescan.

Po351 code car runs fine for the first several miles but then stumbles & misfires at the first 1000 rpms


Here is the code description and the possible causes for the code.

Then, with all that being said, the MOST LIKELY cause of your problem is an ignition coil breaking down after it heats up and is put under load.

sounds like this engine light has been on for a while and codes are piling up, lets start with the po351, note all codes should have a po or a p or b in front of #s.anyway lets go, first is po351 which means you have a bad # 1 ignition coil, replace the coil and check the connection and this will solve that code. next is po420 cat eff below threshold, this means the converter is not working good anymore, but bad oyxgen sensors will cause this code if they are bad and not reading exhaust correctly, you will need to have the o2 sensors tested and also make sure converter is not rattling loose inside shell if it is then cat is bad not o2 sensors, and last code is po545 is ac clutch relay circuit this may be due to a bad ac compressor clutch a blown fuse or bad relay. hope this info is helpful.
