Clean the idle air control valve, EGR/PCV valves and clean the MAF sensor with an electronic cleaner CRC

So if there is something wrong with one of those parts would that cause lights and all that fun stuff to dim in and out with idle or would that prob be battery cause I put in new alternator in sept but I did notice I think battery not right size cause that clamp which holds battery in place is on where its supposed to be but I can lift battery right out of there?
