05 sedan, auto w/ roughly 184k miles.

The best way I can describe this is it�s like my car has the hiccups when stopped at a red light/stop sign or parked. It�s just recently started doing it, not sure why or what could even be causing it. You can feel it vibrate throughout the car when it happens. I�ve recently changed the radiator fan assembly, PCV valve, and one VVT solenoid gasket within the last 500 miles.

Any ideas anyone?

Ugh I hope not, I just had them changed. New plugs don�t even have 1k miles on them.

I kinda wish my check engine light was on so I could at least have an idea of what it could be. The vibration aren�t heavy, very subtle but just heavy enough to be felt from inside the car.

Hmm ok, I�ll scan it and start there.

Interesting. If I look closely I can see the needle jump down & back a hair, but I wasn�t sure if it was just a normal thing at idle OR if the jump is so subtle because the �hiccups� aren�t strong. That�s how little it moves, you wouldn�t notice the needle move if you aren�t staring at it when the car �hiccups�. I did recently have to remove the MAF/intake tube to make room when replacing my radiator fan.
