After i changed all of that the car ran fine for about a week and then the light came back on, engine is idling very rough and when i give it gas to get up to speed it bogs down bad and vibrates. Now the code is saying cylinder misfire 2. What could be my problem. Please helpppppp

did you also change your plug wires in your change over? Have you checked your new code yet? Maybe a similar problem to mine(vacuum leak). I checked/cleaned my: EGR, IAC, MAF, spark plugs, coil packs, fuel injectors, throttle body, and then searched for a vacuum leak. The spark plug was rusty?? Hmmm. Get the code checked and work from there.

Well I fixed the other issues and that was my last one. Try using carb cleaner around your fuel injectors while your car is on, if your hear a change in rpms then I would say that is where your issue is. Good luck
