cylinder 2 & 4 misfire. 05 RS
Changed plugs, wires and coil. Still misfiring on 2 and 4. Any ideas?

^Yeah, let's jump to worst case scenario right off the bat...
Title says 2 and 4, posting says 1 and 4.... which is it? If it's 2 and 4, your cam sensor is kaput. If you're running a lightened flywheel or crank pulley, 1 and 4 are defaults for a false misfire when the engine doesn't really know what's going on. (I have a constant P0304 in my car) If you're all stock, it could be as simple as needing a seafoam and an Italian tune up, or it could indeed be burnt valves; do the simple stuff first. |

I'm sorry. It is 2 and 4. My buddy also said cam sensor. I'll also do a seafoam tomorrow
Thank you |

If it's 2 & 4, your cam sensor may not be to blame. Pull the timing cover and check that you didn't slip a tooth.
