I just changed out my motor mounts yesterday .I went with the solid rubber ones everyone is talking about.After finishing the job I hooked the battery back up and when I started the car it sputtered real bad and then stalled.The car had been running like a top before the mount change.I unhooked the mass air sensor above the filter and it ran better but not great.As soon as I plug the sensor in the car dies.Also there is a whistling sound coming from the back of the motor when it shuts down.Any and all advice will be greatly appreciated.
