recently my check engine light came on and remained on. i pulled a PO304 off the computer. its a cylinder no. 4 misfire detected indication. My plan is to replace the spark plugs and wires as i cant seem to find in my records the last time this was done. i'v also heard it might be my mass air sensor? If i replace my plugs n wires and that actually was the problem, will that clear the code or should i erase it with my scan tool? also what else have you guys seen cause a misfire code?
my car is a 1998 audi A4 with the 2.8 v6 and quatro.

I changed the spark plugs (@ 40k miles) and used some injector cleaner. Mine was intermittent, though, so you might have another problem.

replaced the wire, cleared the code, and voila. I'd reccomend checking to see all your plugs are nice and snug. Also switch your wires around ( like the side they are on) then clear the code and restart. See if it follows the wire. By switching the wires i mean left side goes to right side and disconnect from the "Distributor" Not just switch which ones they plug into. Easy way to tell if it's a wire. Good luck
