Good morning, all! I have a question about my engine idle. I have an 02 F350 automatic and the idle drops and increases while in park. It happens after it has warmed up and randomly. I have already experienced a CPS failure and installed it last week (immediately went to dealer and bought another) and would like to know if there is something else I should be looking at for this? It doesn't seem right that, with all the electronic controls on these newer vehicles, it should have a varying idle.
Thanks for any ideas.
