Hi all, searched but couldn't find this exactly: 98 obw MT with orig ej25. 119K on the clock. TB at 80k. Recently started vibrating regardless of what car is doing i.e. idling, driving fast or slow, low or high rpms, neutral with ebrake on, etc. Does seem worse at higher rpms. Feels like the tempo of a mower handle vibration. Throws no CELs and no more significant noise then usual. Does feel possibly like a loss of some power but may be imagining that. Of course this engine has never run smooth like my 2.2 i had ten years ago or my wife's 05 LTD wagon sohc. No HG issues to date. I replaced nothing recently but a while back (months) did two front axles, plugs (ngk) and oem wires. Swapped coils and ignitors from my sons car to no avail. No signigicant mpg loss.
That's all i can think of
Any ideas would be greatly appreciated
