HELP lim problem

I thought somewhere I read platinum where the recomended but alright looks like I'm picking up new plugs in the am...it has to be something small I'm missing if the car was fine before new parts and no check engine light or anything hopefully that helps it
 


I use ngk v power's. Those are standard coppers right? I know they are not iridium's. And i know they came with them. I bought the car with bosch platinums and had a misfire code. Got rid of them and got bosch wires and ngk v powers. Any1 think i should change plugs?

Coppers are fine, they just don't last as long. but are cheap, so if you are modding and will be changing heat range often, they are nice.
 
i can only assume hes n/a. iridium's will last like 70 to 100,000 miles easy. or change em every 15,000 miles with copper plugs.
 
I was actually considering e3 plugs or maybe even the best bang for your buck iridium. Opinions? Types? 3 prong like the e3 or just regular style. Ive heard stories of the open top style plugs causing bad piston top burns ? Lol idk it's what ive heard
 


You guys would have never thought what was making it idle so bad the dam pcv valve o-ring I knew it had the big one on the top but not a smaller one on the bottom must have fell out when replaced back to 100% .....so in case some one else has the problem and replaced a pcv double check it
