Cylinder 2 & 5 misfire

N54_wagz · Yesterday, 08:06 PM

I cannot figure out the issue, the car used to misfire on cold start but the plugs are only 3k miles old, I’ve tried coil packs, and I’ve replaced the injectors. Which replacing them seemed to get rid of the cold start misfire but under casual driving the codes come back but under hard driving there’s no issues, I’m tempted to throw new plugs in it.. again.

( this is also a “new” engine that I’ve refreshed )

Did this issue happen before you replaced the plugs?

I’ve only put 3k miles on the engine since I installed it refurbished it, so there’s no history before these plugs
