i have a 06 Evolution SE..The CEL came on and the codes say misfire in cylinder #2 and #4 (i believe) the problem is if im in a high gear low boost situation the car will sputter while its building boost. Another time it does it is when you just get on it 1st 2nd and 3rd gear are fine but in 4th and 5th in boost it will sputter...only thing thats done to the car is a Ported turbo and manifold, buschur IC piping, 3" Buschur TBE, and a HKS SSQV bov recirculated...

Any suggestions??? ive heard replace coilpacks and wires?? i replaced spark plugs already and still does it

 

nothing?..haha

 

My IX did the same thing. I changed the spark plug boots and wires and it fixed the problem instantly. Could be a bad coil though too. Good luck.

 

sounds like plug to me but im far from an expert haha

 

thanks guys might as well buy some good coils and wires while im at it

 

I your going to try new coils, wires and boots you might want to try this. https://www.evolutionm.net/forums/se...installed.html I have one and I love it so does everyone else. It will most likely save you money too. Good luck.

 

i had the same problem. i re-gapped my plugs and that fixed it.
