I have a 2002 WRX Wagon that just coded for a #3 Cylinder misfire (it has been idling rough lately)
When I look up the prices for a coil 'pack' & I see $90 - $110 is that for all 4? Or for EACH one?
What parts should I get for a tune up? Plugs, wires(?) and just the misbehaving coil (if that price is each)?
Any insight would be greatly appreciated
