Hi everyone I'm new here I have an 02 max se I have 3 questions. First one. Is changing the rod bearings hard to do, do I have to take out the block, what are signs of them going bad?. The other one is recently I changed my fuel vapor canister as well the purge valve, oil pressure switch I also flushed and changed the coolant. After doing all of this I noticed when my car idles at stops their is a slight trembling that is felt rpms doesn't fluctuate or bogs down when I step on the gas.

 

Have you ever changed either of the camshaft position sensors? They tend to go bad on these motors and that hesitation you feel at idle could be one of them on the way out (if they haven't been changed yet).
