Replaced 2 motor mounts and the issue seemed resolved for a short period and then returned. The big yellow triangle and check engine light came on, Service transmission light came on. All reset after a couple days, then only the regular Service required light came on. Now the windshield wipers speed up on their own and the heat automatically raised on its own for a short period of time. Loud knocks, revving, and bucking only after the engine gets warm. Drives beautifully when it first starts up.
