see i thought the same thing, why would it rev different, for some reason it does tho. i havent checked the crank position sensor, but now that its said ill check it. the engine will gradually let me get up to speed, but if i mash the gas, it almost shuts down completly, so im thinking its a sensor somewhere if not the crank position sensor. thanks for the help and will get back soon to reply with what it may be!
