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.
