So I'm a newbie, and I did my first spark plug swap on an 03 Wrx. I reviewed the tutorial that was posted on this site... (Very Helpful by the way) After I put everything back together and fired it up for the first time, it sounds like I'm only running on 2 cylinders. My first thought is that I put the coil packs back in the wrong place and the engine is miss firing as a result. Is this even possible? If so How do I know which coil pack is in the wrong place. I'm nervouse to drive it somewhere to have it checked. Aslo, I gapped my Autolite Double Platinum plugs to .028. Could that be causing any problem?
