Jeep Information

So after replacing, PCM, distributor, cap, rotor, pick up coil, plugs, wires, TPS, IAC, CKP, ignition coil,checked fuel pressure, fuel filter, full oil change, checked battery and alternator....

It will run great at times and today took about 10 seconds of cranking before it finally turned over. Before it started but does right out (sputtering). I got the codes only two. (p0351) (p0420) the 420 is misfire which I get. The 351 relates to ignition. I did hear that not putting the "copper tip" plugs back in can cause a misfire, but stalling??

Any ideas? 96 grand Cherokee 4.0l
