Issue:
Heavy Engine vibrations at 900-1.1k, 2k, and 3k while in idle. No vibrations when in gear.

Parts already replaced:
- Transmission mount
- Engine mount
- Spark plugs
- Spark plug coils
- Air filter
- Cleaned MAF

Left to do:
- Run smoke test on intake
- Replace MAF if necessary
- Replace DMF if vibrations are still present
- Solve world hunger
