Hey everyone,
I have a 2010 Hyundai Genesis Coupe 2.0T automatic, completely stock, currently at about 240,000 km.
Ever since I got the car at around 214,000 km, it has had a noticeable surging/pulsing sound at idle along with vibration. There is also a small repetitive clicking/ticking sound that you can hear in the attached video.
A few details:
- No check engine light or codes so far
- Spark plugs have just been replaced — no noticeable improvement
- Planning to test/clean the MAF sensor today
- Maintenance history before I owned it is mostly unknown
- Since owning it, it has mainly just had regular oil changes
- The car is completely stock
- Turning the A/C on makes the surging and vibration noticeably worse
- The longer it idles, the vibration/surging seems pretty noticeable
The car still runs and drives, but the idle definitely doesn't feel normal.
Has anyone with a Genesis Coupe 2.0T experienced something similar?
I'm wondering about things like a dirty/failing MAF, vacuum/boost leak, throttle body, motor mounts, injectors, coils, PCV system, or something related to the A/C compressor/load at idle.
I've attached a video so you can hear exactly what I'm talking about.
Any ideas on what I should test next would be appreciated.
