So yesterday after driving my fit for awhile, it started having a heavy vibration under load. It only happens when i am in drive. When i hold the brake and give it gas it also does it but never while in reverse. It has about 88 thousand miles and i have maintained regular oil changes and maintenance. I was thinking maybe motor mounts but when i looked at them last night they looked fine. Kind of at a loss, any suggestions would be appreciated!

 

Vibration or misfire?
Hardened motor mounts will cause vibration at the steering wheel when holding brake in drive. It will slowly go away as car begins to roll. The stiff mounts causing vibration that is ambient temperature (vibrates at 40 F but not at 60 F) and rpm sensitive (at 1000 rpm vibrates at floor board at 500 rpm vibrates at armrests)
