By white you mean the top side??? The actual spark plug surface shouldnt be white.... It will have carbon build up and be black... Your checking the gaps, making sure the material doesnt look "welded"

Hello
I was checking the spark electrode end gaps where within spec.
All the plugs looked on the whitish grey side, with alittle carbon build up.
the e3 s are still in there. The missing issue was there before them and didnt change after I had them installed. I had them installed when I did the o2s (all of them) I was getting P0174, P0171 lean condition set codes.
The missing got a lot better after I did the wires. But its still there, and now its constant at Idle, Its also shifting from closed loop to open loop fuel trim.
I'm really leaning toward it being a PCM issue as the last code I code was P0053 resistance o2 bank1 sensor1 PCM. So I will try to get a coil tester and see if its a coil causing the problem. And may be reinstall the original spark plugs. as they look great. They are the oem iridium.

unplug injectors at idle to pinpoint the missing cylinder. I've seen bad coils also cause what youre experiencing. With all the issues you have going on at once, have you gone over the engine harness and looked for something rubbed or chaffed? its very possible in a van especially where everything is pretty tight.
and for the love of Bob... get the E3's out of it...

I know for a fact the E3 cause a problem. My buddy had bought a 06 crew cab it had a little miss around 1500rpms. I had read that E3 were junk, so I replace them with my old iridium plugs I pulled out my truck. His problem was fixed.

easier way to find misfiring cylinder... get a spray bottle with water. squirt water onto each cylinders "tube" of the exhuast manifold. if it the water doesnt hiss and turn to steam instantly, then that cylinder is misfiring.

I still haven't replaced the e3 s,
I will get to it this weekend. Today I had a crazy thing happen.
I needed gas last night a few blocks from my house but was to tired to get, This morning I drove 6 blocks and put $20.00 in, little over 5 gallons, I drove 31.5 miles and the light came back on! I could not believe that! its never happened! 6miles per gallon!
Whats up! No one can understand whats up with this thing!
Could my really poor gas mileage along with the list of issues ring any bells with anyone?
Im ready to scrap this thing and Buy the Nissan NV2500!
