2017 Chrysler Pacifica question. I am confused about work done to my 2017 Chrysler Pacifica. Engine was running rough. Took it in to be serviced. "CEL CODE IS P0305" The mechanic replaced the fuel injector, spark plug, and first defense fuel 2 pk.
1 month later, while on vacation, the engine light came on and engine running rough again. Luckily, a Chrysler dealership was close by. Their diagnosis was "Found CYL 1 119PSI, CYL2 96PSI, CYL3 114PSI, CYL5 68PSI, CYL6 68PSI. Performed clinder leak down test Cylinders 1 - 4 had almost no leakage. Cylinders 5 and 6 are leaking into cooling system indicating failed cylinder head gaskets."
I'm confused how there can be 2 different fixes for the same problem.
