Mates car, diagnostic is showing error codes random/multiple cylinder misfire, cylinder 1 misfire and oxygen sensor b1-s2.

Who thinks I can change the pre cat lambda and that'll fix it?

Oh I was also thinking that with it having the misfire specifically on one cylinder as well it could be the coil pack at fault?

i've known a few puntos needing a new coilpack.

I dont think the 02 sensor will cause your miss fire could be wrong but i think its 2 different problems

Depending on the age of the car, it may be an ECU on the back of the throttlebody if i remember right. Very guilty of going.
