Got a misfire merging onto the highway (at WOT) the other day. Only codes I got were misfire cyl. 5 and fuel pump plausibility. I know the fuel pump code doesn't always mean something is wrong, but I've never had it appear before. Thoughts? Plugs are 20K old so they may be due, though I was leaning towards coils (at 55k miles). Hoping its not a fuel pump...
