Car has the hiccups?
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? |
Have you checked the spark plugs and gap? Maybe it's misfiring.

Sounds like a misfire. Since you recently did the VVT solenoid gasket I would keep that as an area of concern in your mind. When I got the P0021 code, I was only slightly low on oil (not even halfway down the hashed area). I topped it up and it hasn't come back since

I would scan it for codes anyway. Just because the CEL light is not lit doesn't mean it might have pending codes. It sucks when you have a faulty coil or VVT solenoid and don't have another car to swap and test them.

if the idle's dropping when that happens I had that problem and fixed it by cleaning intake MAF and throttle body

At its worst I'd idle drop and shudder every 2 seconds. After cleaning the above it only happens occasionally after minutes of idling. If you're on OEM engine mounts might wanna look at those too, they should absorb most vibes from a small idle drop. I feel it because I'm running poly engine/trans mounts.

Listen to the exhaust at the tailpipe, that's the heartbeat of the engine. It should sound perfectly rhythmic and you will year if there is a miss.
This helps eliminate various other sounds you might hear by trying to listen at the engine bay. |
Edit: yep, double posted...
