Try a tune up first.

Re: how to fix power loss?

I see that you have a K&N filter- I have one in my wife's '02 V6, too. Her car started to lose power, so I went to the parts store and bought a can of spray mass air flow sensor cleaner. Sprayed out the meter and the intake- it really brought the lost power back! It seems that the oil from the filter gets into the MAF sensor and gums it up. Do not use anything BUT MAF cleaner! Carb cleaner, brake cleaner, etc. will damage the sensor.

If that doesn't do the trick, I would have the O2 sensors looked at.

Yeah I'll try that that would make sense ause it also hesitates sometimes. I'm definetly not gonna use carb or brake cleaner on something that sensitive

Dude, good old fashion tune up. Also, you might wanna look into coils. I replaced mine and my car turned into a wholeee neww beasttt. Especially if you feel like theirs a miss-fire, the coils go bad a bunch

No kidding- my "butt dyno" said that I picked up 15-20 HP. It was really gummed up. I guess I over-oiled the filter.....
