Hi I have recently joined this forum. I did not know how to post on my phone so I replied to this thread. I recently got a 2008 evo x in may. It has an fp green turbo, cams and springs done, walbro fuel pump, 800cc injectors, intercooler, intercooler piping, catch can, turbo smart bov, air intake ect. Everything was done to the car at lighspeed innobations up in red deer about 20000 km ago. When I bought the car it had 47000km on it. The previous owner had the stock exhuast put on it because the aftermarket one cracked. So recently I decided to put the agency power catback exhaust back on since the car was tuned with it on. The car was tuned with an cobb access port and it seemed to run fine as I got it with 47 k and drove it 5k. Now. The car has 52000 km on. So here is where the stuff started going wrong. When I got the exhaust on the car was running good. However the afr's were higher on average about .5. My ccar was also overboosting. When I was coming from work one day the check engine light came one. And the car starting shaking violently on the highway. So I pulled over and read the code. It was a p0302 which is cylinder 2 misfire. I drove it home as I was close to my house. The car was running VERY lean at this point. The afr's were at 17-18 and it would rev up and down at idle. VERY abnormaly. So I decided to check the sparkplugs and found that my cylinder 2 spark plug was cracked. A small piece of the tip had simply broken off ( about 1mm).. So I went and bought new spark plugs. My cousin also took a boroscope and checked all cylinders and they all looked the same. When I changed the sparkplugs none of the issues were resolved. Later on I did a compression test and found out my clinder 2 had little to no compression. . So I have recently bought my evo x and have blown my engine. I don't know what to do. My car is still under warranty and I have EVERY stock part. I waswondering if I put all the stock parts back and took it to the dealer if they would notice. I do not know what to do. Any help would be great as this is my first car. Thanks

 

might not

 

!It might be cheaper just to have a performance shop take a look at it. If mitsu sees it you'll have to put all the stock partts back on, de-tune, have them re run all necessary tests to find out the root cause, and in the end they still might void out the warranty anyway.. goodluck though
