yes i do have the APP104 plugs in there because i was hoping to start getting more mods on to get a pully soon but money is tight now. The other thing is it had the misfire on the old plugs i pulled out which were stock from what i remember. And the 104's i have in there are gapped at .055. So i wouldnt think it was the plugs but i may be wrong and probably later tonight i will try to unplug the maf and see if it changes.
