I just started having a problem where my rpms have gone bonkers, today while driving my rpms went from normal to going below the 1, then with my foot on the brake at a stoplight It would jerk forward and the rpms would jump to 3, like it was stalling out then super boost foreward. What is the likely cause of this?

You may have a vacuum leak, get a can of spray gumout, spray the vac lines and maniflod area, when the idle changes, youve found the leak! You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs! If that doesnt do it, you may need a new idle air control valve, it's bolted to the throttlebody
Is the check engine light on yet?
