Well, i dont know where to start.. i have a 2008 evo x gsr fully built 2.3L, had the car for 2years no problems whatsoever.

The other day when i just got off the highway the car began struggling to stay running and eventually stalled. Had code ***** do not remember but access port claimed it was a multiple missfire.

Now i have to clear the code to get the car to stay running, but once i go for a spin it begins to do the same thing? struggles to run and eventually stalls.

So far i pulled the plugs 3 were okay, but last one closest to the chain (not sure if its 1 or 4) was fouled, as black as can be.
