Car runs great, just replaced timing belt kit and water pump and battery. At a full stop foot on brake the engines runs great however the vibration begins. Engine never shuts off just get a hard vibration. This started way way after repairs, engine run great. Thanks for the help!

Hello,

It sounds like you have low compression on one cylinder. Here is a guide so you can confirm. if you do not have a gauge you can rent one from the auto parts store for free.
