I have a 2002 Saturn SL1 with 85k miles on it. Today I had to take it into the shop because the engine light came on. I was told the Error codes are as follows:
po300, po340, po341 and po442. Now I did some digging and was told to replace the ICM and coils. I did that and it still miss-fires.A lot more actually. I tried new plugs and still the same problem. Now i'd like to get it fixed by myself. Should replacing the Crank Position Sensor resolve my issues? With the po442 code would I be correct in saying I need a new EGR valve?
