so i installed NGK spark plugs a while back with the stock gap at .32. I know stubid but i didnt realize evo sp gap is suppose to be.26.

But my car runs fine it doesnt missfire. It idles werid at times givving a little stumble once in a while.

my afr is rich then it gets really lean about 10s and it knocks alot when i get close to the 6k rpm

could the wrong gap be the cause of that?

and is it ok to just pull them out a re-gap um?

thanks guys

 

nothing?

 

yes re-gap them to 26.

 

Which NGK did you put in?

BPR7Es are a little colder than stock so 0.26 is a good gap
BPR8ES are colder and shouldn't be gapped past 0.24
