having trouble finding misfire

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.
 


ok guys im at a loss the MAf looks new and is working fine. The wires look to be giving good spark to the plugs. Just got a few more questions...1. is there any possibility a clogged cat can cause a misfire only at idle? 2. if the misfire is mechanical basically burnt valve or something along those line wouldn't you be hearing something else other than just the misfire an wouldn't it be a constant misfire? any wild and crazy ideas as to how i find where the misfire is coming from? :th_scratchhead:
 
Do what bluegtp91 said find somewhere to get or rent a bore scope and check out the cylinder, said lady could have been lying stock lims are plastic on these cars and do go out. How many miles are on the car?
 
yeah ill be going to a friends house and he may have one so hopefully i can get this misfire gone soon cuz now its holding me back from getting an emissions on the car and it tagged properly...
 
well I would recomend a compression test and a cyclinder leak down test from these two tests we can determine a few other things
