Need help I replaced on my 98 c1500 spark plug and wires, distributor cap and rotor, ignition coil, and ignition control module. Well I put a delphi ICM and the p1351 code pops up so I put the original oem one back on and the p1351 goes away. I returned the new icm and bought a different one from a different brand and it does the same code but the old one takes the code away. Any thoughts on what it may be? TIA
