I've owned my 2010 TSX with tech package since 2017. I love my vehicle, but let's face it; it's getting old. The vehicle now has 161,000 miles and, believe it or not, runs great and looks great, except for some normal cosmetic issues.

I'm continuing to have a disturbing issue that on occasion, when stopped (that's when it's noticeable), the engine will have an annoying vibration/run rough. My mechanic and I have been trying to duplicate and locate the source. Plugs/coils good, all fluids serviced regularly, mounts/shocks are good. I think I may have narrowed it down to the A/C compressor. It seems when the compressor kicks on, the car starts running rough (might be my imagination). The compressor is original and the A/C is running fine.

Has anyone else had this issue with similar findings? I would really like to solve this issue! It's definitely annoying.

Thank you!

 

Motor mounts and vacuum control for the mounts needs to be looked at
