The best that I can explain it in words is that, when my car is on, fully warmed up, the car is in park, the engine "shutters" very gently, just enough to feel a slight vibration when sitting inside. It shutters in rhythm inbetween pauses of smooth idle. I can notice only when I really pay attention. My car is an 03' with 40k miles. Could it be that i have to clean out something already?! EGR or something like that? I'm not sure.

 

I think thats normal? My old motor did this and my type-s motor has the slight vibe in teh way you describe it

 

is it? ahaha.. i am relieved if it is. i am so paranoid about this car. thanks kris.

 

i have an 03 TLs with 50k miles and it does the same thing when in park, or neutral, but doesn't seem to happen in drive. It must be normal.

 

^ yep thats the only time i ever noticed it

 

have on 03TLS 106k (drive it alot lol)and it has the same vibrations,,, exactly as u discribed...I thought i needed new plugs 2, think u just saved me some $ ..my 2000 accord v6 always has that too

 

Mine does it too but I know also if you have the AC on it you can feel that more and you can feel that switch on and off.

 

same situations as the others
