So I have been chasing issues on my car for a while. It’s a 2005 legacy GT manual trans. I had a misfire codes for cylinder 2 a few months back and ended up having a blown head gasket. I replaced the head gasket and all the seals, had the heads machined, and valves cleaned.
The car still had a few minor codes that were related to the maf and were easy fixes. Once I had all codes cleared and started running the car frequently I received another p0302 cylinder 2 misfire.
The other code I am having problems trying to fix is the p2021. I did originally install the tps incorrectly but have since installed it properly with no fix. So after no resolve I bought a new sensor and the code finally cleared. After my second start up with the new sensor code p2021 and the p0302 came up. I do not know where to go from here and am a little sick of throwing money at the car.
