Do the RPMs just randomly just jump, or is it doing this when you are trying to accelerate?

Random

Make sure the brake light switch is ok ( not touchy ),,, If you tap the brake pedal while excellerating, it will slip the convertor, which is normal.

When my car got tuned, the tuner told me i was loosing a ton of power up top cus my converter would just unlock at high rpms and thinking back mine kinda did what you are talking about. It could be more of a computer related issue. I would take the opportunity to just have it tuned now and see what happens from there.

I would agree that a converter radonly locking and unlocking is a tuning issue, ENGINE MISSFIRE COMES TO MIND.

If My Idel Is Low Would That Have Anything To Do Wit It ? You Guys Realy Think Its A Tuning Issue?
