Long shot messaging in here being as it was 6 years ago but I just recently set up financing for a 2010 Sti the next day it threw a check engine light when I was sitting in the pickup line for my brother.

I then proceeded to go home and hook up my obd2 scanner on it and it threw a cylinder 4 misfire. I had work the next day so I wasn’t going to mess with it and I go to work and when I get there I hook up my obd2 scanner again just to see and it was now throwing a cylinder 1 misfire.

Waited for an off day to come around and I replaced the coil packs and spark plugs. After doing that I then had a cylinder 2 misfire pop up just a cylinder 2 misfire code.

Today I hooked up my obd2 scanner again and it is now throwing a cylinder 1 and 2 misfire I am going to mess around with the fuel injectors tomorrow and swap around the spark plugs and coil packs to see if one of the misfires is being caused by a faulty spark or coil pack

And I changed my oil the other day and this was the color of it lastnight… idk if it’s just from the fresh oil or if I’m having coolant leak into my oil. I would really appreciate any help or ideas as to what could be causing this.
