Hey guys,
I'm searching for solutions to my problem, I've searched a few threads but some of them only have the issue when accelerating at mid-rpms, mine only happens at low-rpms and mainly when the car is cold.
I am having errors P0300 and P0302. The dealer told me I need to clean my injectors and valves and offered me a package for ~$200 dlls. I told him, what about the coils? he said if it was the coils the car wouldn't run properly. They also said they checked the spark plugs and they were fine.
My check engine only comes on in the mornings when the car is cold but the dealer tested it when it was warm a few minutes ago and 2 malfunctions were detected. Basically at cold startup it shakes a lot and it hesitates to go, when it's warm it acts perfectly normal, except at stop lights when you can kind of 'feel' the misfires or something going on in the engine.
Error P300 is random/multiply cylinder misfire detected and P302 is cylinder 2 misfire detected.
Here's a video:

My car is 57k miles, so I could still be covered by the 60k powertrain warranty but since they just replaced an intake manifold sensor under warranty (error p2015) and I'm Stage 2, I don't want to push it.. if it's something I can replace I will do it by myself.
Thanks for your help!
Updates (issue not fixed yet):
Car is 58k miles now
Replaced coils with r8 coils
Replaced spark plugs with NGK Platinum's
Misfires detected on cilnders 1,2,3.
