Since I purchased this pilot 3 years ago, it has had a shudder at idle. Its not mounts or anything like that, it feels like its the engine/fuel/battery. It was a lot worse when I got it, thats when I went tracking the issue down. Cleaned the top end + intake manifold + throttle body, did timing chain, mount, water pump, OEM recommended plugs and coil packs. I don't remember what the plugs were, but the coil packs are denso. Replaced the battery and cables as well. I'm not sure what helped the shuddering, but something did, because its a lot better. Since then, its been a mild shudder, but its still there. Now it seems to be getting a little worse.
What do you think it could be? Anyone had similar issues? Common vacuum leak? Alternator? Dirty injectors?
