ya i been having problems with miss firing now, i have BR7ES in at like gap 22-23 and high rpm its mis fire, i dont know maybe time to go colder now? any one?

 

seriously if u cant change a spark plug on an evo (which is extremely easy compared to other cars) maybe its cuz ur a girl who doesnt wanna break any fingernail? lol. 4g36 engine is probably the easiest i've ever done. remove the plastic cover with a few tiny bolts, and only a few more sec to pull off the two units sitting on top.... the spark plugs arent that deep in the evo... DONE lol
