Ok thanks, Ill grab a fuel filter and replace it tomorrow and let you guys know how it goes. Hopefully thats it.

good luck. It wouldn't hurt to take your MAF out and give it a spray withe the K&N once an awhile. Let us know how you make out.

Well I replaced the fuel filter and that was it. It is way more responsive and has more power now. The shifts are perfect. Thanks a lot for the help guys.

Glad we could help.

Did you change your transmission spin on filter also?

Yeah I did that a few weeks ago.

I have the same problem! I'll have to try the change-the-fuel-filter trick.

I would not hit it with compressed air, those wire are really small and delicate. Just pick up some CRF MAF sensor cleaner, it can be bought at most of the chain auto parts stores cheap enough. If you have a Oiled air filter, it is a good idea to clean the sensor off every once in awhile as sometimes the oil can get sucked off and coat the MAF sensor giving false readings.
