3rd gear studder

Alright, here recently I have noticed the Evo has some issues while in 3rd gear. When you are on it and the RPM's get around 5K rpm's, the car feels like it studders, just for a second. Then it picks back up if you stay on the throttle. Car is in full boost. It doesn't do it in any other gear, just 3rd. And it doesn't do it all the time, kind of randomly. I experienced the same problem once before (had water around the spark plug cylinder) but I checked all the plugs and everything is fine. Anyone have any ideas?

Car just turned 12K miles on OEM plugs. Would that possibly be the culprit?

Thanks.

What mods do you have? Stock boost levels?

If you're running higher boost levels, it's probably knock.. especially if you're running a aftermarket open element filter.

Hmm, i've got a MBC turned to 20-21ish PSI with an HKS RS intake and I don't get this...

what exactly is your boost level? are you reading this from a boost gauge?

Before you get too involved or concerned, it actually sounds like a misfire.. If you haven't replaced your plugs yet, you might want to..

I will try replacing my plugs before I do anything else. Thanks Malibu. If not, I will be back.

Does anyone know if you can pick up the OEM plugs at AutoZone or PepBoys or do I have to get them from the dealership? I can't remember what brands they carry...

Thanks for the info guys.
