You should be getting ready for the 3rd plug change due at 90k,coppers only and change every 30k.Tkaes like 20mins to chnage the plugs in a Liberty.
A bad battery can cause funky issues in a Liberty,even ones that test good but none of your issues will be caused by a bad battery.Large temp changes are why your TPMS light goes on/off.Several issues can cause the ABS/trac lights to come off/on.Worn plugs can cause your acceleration issue alnog with several other maintenance items.
