Needing some input on a gaggle of codes that just showed up. A little history: 2002 3L Accord EX 4dr 214K mi No mods New timing belt at 130K mi, 9 years ago I did plugs, coil packs and adjusted valves at 211k mi that got rid of a P1399 code that was rough at idle and running. Now, it sputters at idle, but runs smooth, at times, in neutral revved up. When driving it sputters under acceleration or under load, like up a hill, but smooth when cruising. I drove it new off the lot March 17th, 2002. Never anything significant replaced. It's been a boringly reliable vehicle. What could be the cause of all the codes at once? I know I'm in the neighborhood of, or beyond, needing the timing belt replaced again. I was wondering if these are codes that will show up shortly before the timing belt goes. Thanks for any input anyone can give me, it's greatly appreciated.
