P0401 is Egr insufficient flow Try getting a handheld vacuum pump and apply vacuum to the egr valve at idle, w/ vacuum apllied the car should run rough. If nothing changed then something is clogged.

If eveything checks out you got a bad manifold differential pressure sensor.

I tell you this car as been nothing but a headache ever since i bought it. 28k miles on it when I bought it from carmax in Conneticute and my list of problems : 1. all 4 rotors wrapped and pads paper thin. ( this is how they sold me the car) 2. Heat sheild on downpipe rooted and falling off car . also how they sold it to me 3. poor shifting and tranny just getting worse 4. check engine light comes on after 20 miles of driving it off dealer lot and still on due to p0401 code 5. after new brakes done , imporper install on rear pads . Had to fix myself 6. rear diff , tranny and tc oil never changed , evo needs its oil in thoses area changed every 6k to 9k. I'm so ready to drive it off a cliff. I'm going to look at a 2006 evo 9 SE. I don't know if anyone as heard of it or seen it , but looks pretty hot . Mr bbs wheels , mr black out tail lights , se red badge on car , hid's , sun roof. only 12k on it and they want 29,000 for it. I think i'm just going to trade me evo 8 in and pass the problems on to another dealer. I pulled the check in light bulb so they can deal with the crap . i'll my intake out and put the stock on back.

All IX have black out lights. a SE is just an MR except with the 5spd which is the better tranny. The SE is one of the better Evo models IMO. Keep in mind a used Evo youll have a chance to have problems with it. besides that the pad,rotors, tires, and clutch all suck and only last about 20k. the fluids should be changed on the regular. the tranny and TC need to be done every 6k and rear diff every 12k or so. Honestly though all your troubles fall under the warrenty and you should put your car back to stock and have mitsu deal with it.
