Lee what is the stock plug number? Is it a 3925 or 3927 My car is acting up again so I carried it to the dyno and tried a new ecm no change then we tried a new mass air no change. The only thing we know is the plugs are getting gas fouled on two sets of plugs so we decided to go to a hotter plug to see if it is the culprit of my aggravation  The car is hard to start and will not rev past 6 grand plus is popping and snapping Thanks Steven

3925 is stock equivalent
You have something else going on if you are fouling 3923's |

MAF wiring issue? Bad TFI on distributor?
Fouling only a couple plugs huh? ...injectors bad? valve guides?

Well it is fouling all 8 plugs, not likely to be bad injectors being all the plugs are fouled. We checked alot of stuf last night and I said I doubt it is the plugs being I changed them and they fouled out real quick but they insisted it could be the hole problem so instead of getting pissed I said ok what ever. We change the mass air flow sensor out with a new one with no change but did not check the wires. I also changed the module out on the distributor also no change. Going back tonight to see if I can figure it out.

Can't see the valve guides doing it..
What MAF and injector setup do you have? Didn't you say someone tuned the car for you a few weeks ago? Did they actually tune it or just do some dizzy and fuel press adjustments? What a/f is the car laying down now on motor?

well the culprit is the tube that runs from the MAF to the throttle body. The tube was deformed to say the least went to change the plugs and noticed a blockage in the pipe witch is no longer there and it will now rev to the moon
