replacing plugs is a start could be the wires also.

How did you clean the maf you want to use break cleaner and really hose it down or some solvent that will completely evaporate and leave no residue.

oh and i see your FI Id be interested in what the plugs look like if they are missing grounding straps then you really need to look at the tune and count your stars
