Blah. It drove fine today at lunch. Then on the way home it started acting up again. I'm having the local shop look at it; they will check it out for free. I'll post what they find.

Yes. 87 is bad. It probably wouldnt stutter though but could hurt the motor. Check your receipt. first get good gas in the car.
The cel light is gone but the code is stored. Get a code reader and see what it says. Auto zone has them to borrow I think.
Evo x plugs are iridium and don't get tapped. They could be bad, but gap isn't it.
No way to check you MAF sensor, replace it and see if you are fixed.

Ok, the mechanic called and said the plugs are fine. He drove it and said he couldn't tell that anything was wrong. Typical........I told him to make sure he's letting it warm up before taking it out since the ECU keeps the boost conservative for a few minutes if it's been off for a while. I'm gonna put my head through the monitor if it never acts up on him.

Is this mechanic also a tuner with a dyno? I wonder what he is doing to indicate the plugs are fine? In mine, when it has been a little stuttery I just swap the plugs and it goes away. The plugs look fine but at WOT they seem tired. If you can't find anything else wrong you might just try putting in a fresh set, at $45 it will cross it off the list.
If it isn't the plugs and everything seems tight and no codes, you need a full service shop that can get the car on a dyno, evaluate your tune and really check out what is going on, even at WOT. A quick turn around the block won't do that. If you haven't yet, find that shop.

Now-a-days you cant take a car this advanced to your local grease monkey, unless he specializes in Japanese car/ Mitsubishi engines. I showed my car to my family mechanic at the gas station and his eyes were bulging from behind his glasses when i popped the hood. He said, "Where you go and get this computer from? Lawd have mercy, ima have to drag my son off that damn xbox and come look at this, it might be time for me to retire mmm mmm mmm." lmao

Ok the mechanic took it out again today. He let it warm up for 5 minutes before driving it, and he said it failed in a most violent manner LOL. They read the codes and it says bad plugs!! Plugs are being overnighted to their shop and I should have it back tomorrow. Looks like a lot of you guys were right! Thanks for all the help.

Glad it is sorted. Buy another set, good to have a spare...

Oh my GOD. I got a call from the mechanic today. The plugs didn't fix the problem at all!!! He is refusing to try anything else because he admits that it would just be a shot in the dark. I have the car back now and it's hesitating and missing like hell still, even with brand new iridium plugs. UGH
Does anyone know of a reputable tuner in the Winston-Salem, NC area? The last time I got my car tuned was 2.5 years ago. Maybe something has changed since then, but there was nobody within 60 miles of me that could do it in 2009.
If my car does need a re-tune, how did this happen? Why would the car run PERFECT for 2.5 years and then all of a sudden need a re-tune?

How many miles do you have on it? Dont want to sound like a broken record but check the timing chain for stretch. It sounds as if you're in limp mode so its something significant. I've had issues with timing chain on my 08. From what I've seen it happens around the 60k mile mark.
