So the previous owner said when he hooked the car on a diagnostic machine, he got a O2 sensor error. This morning i managed to change both, but i dont have a diagnostic machine, so the error is not cleared hence there is still ',check engine', light. The thing is when we test all the coilpacks, number 3 is not making any noise change when we pull the plug out. The coil is fine cause wenswaped them around and got the same result. Could it be a bad valve not totally sealing? or
Could this be due to the error code that is not cleared?
