Is the engine running rough only when revved above a certain rpm? or even at idle...? if it's stumbling even at idle, try and pull the maf plug as the engine is running... if it smooths out, then that is a tell-tale sign of bad maf/maf connection. Just a quick test to try only if the rough running is at idle...
