Possibly... But check the plugs first. As they are wayyyyy cheaper to replace than coils and wires.

 

Hmmmm 70K on the odo; it also could be an injector issue, who did the tune? Ahhhh disregard... plugs first, check for leaks, and clean your maf sensor(with MAF sensor cleaner... NOT brake cleaner).

 

will pick up some maf sensor cleaner tmrw and gap plugs. Huge snow storm in Houghton MI as we speak Over a foot of snow in the last 3 hrs.

 

When I put a k&n intake on my IX MR without a tune it did the same thing. I would get a tune. With that intake, from what ive read its not always good to get an aftermarker intake with out a tune

 

Would like to get it tuned.Perrin intake and catback stealth exhaust has been on the car for at least 2 years now

 

Awwww Man no tune... No Deal! 2 years you've been cruising around like that, No Bueno You gotta do dilligence bro.

 

A tune may make a difference. Depending on your location. MAP may be only a few hours drive. And plus it would really open your car up. With your mods.

 

Lol the tune is not his problem .... He will be a bit leaner but only during peak boost, and that wont be lean enough cause the misfires.

But yes you should go get a tune , the evo deserves a better tune then what comes from factory (poop) :-)
