yea.. i guess what im trying to say is that without logging, its a crap shoot. Unless you can see/hear/smell something obvious.
OP if you cant log/dont have a cable/have no interest in logging
At 43K yes do your self a favor and change plugs. Change the oil too and the air filter. Other than that, if you still have issues you have to get some real info from your car and logging is the easiest way to do so.
