everytime the car is in od, and rpms are low, and around 40-45mph it seems to stumble a lil at part throttle. then catches itself and runs fine. it feels as if i hit a bump in the road or something, like a slight jerk/tumble. and only seems to happen at part throttle in od at that speed. plugs look good but are almost 2 years old. rotor is a lil rusty on tip. fuel filter is about 2 years old as well. no codes at all. any ideas?

Also, see if your MAF sensor is really dirty. If so, clean it with some MAF cleaner you can get at a local auto parts store. If it is extremely dirty can cause the stumbling you are describing. Oh, and make sure your timing is at 10 degrees.
