Does it do it in a certain gear?( I assume it happens in 4th)..Try & see if it does it in 3rd.
-Check your codes(if any) in the PCM.
-Check your transmission fluid for both correct fluid quantity & condition.
-Look over your engine for anything obvious,with special attention to the coil packs & ignition wires.
-check for any air leaks down stream of the MAF.
What kind of fuel do you use?
Did you recently change brands/octane ratings?

By all means take the car to a shop if you're new to the hobby or otherwise just not well versed automotive diagnostics/repair.
If I were you,get ahold of the owners manual & just read through it..& look at what needs to be done at various mileage intervals..
Go with the "city /short trip" schedule.
Being a novice, you'd be suprisedwhat you might learn just by reading the owners manual.

i am experiencing the same thing at 2000 rpm. I am going to start with a fuel filter and plugs. Does anybody know if a cam or crank position sensor could cause the same problem?
