C43 cylinder #2 & #4 misfire suspect bad coils
The car is pulling strong for 5-150 km, then the CEL light is back on.
Always the same error.
Give me ideeas please !
First time it happend is after i stage 1 the car !
Same tuner, other c43, no problems !
I had the same problem a year ago. Same cylinder and did the cool and wire along with plug swap and problem still there. I bought a brand new coil and it fixed it. Not saying to buy a new one but that's what finally worked for me.
