OK silly idea. Intake charge pipe? 'Cause a vacuum leak would definitely cause sputtering and misfires. But would it throw AF ratios off enough to make the ECU think it's a misfire.
FWIW, I replaced my charge pipe at 55k miles. The pipe was OK, but all the stupid plastic fittings/nipples to it/around it were brittle as hell. Given all the plastic under the hood, I can't see how at over 90k that stuff wouldn't start cracking up.
