My 2005 Quest has been starting slow lately (sounds like the engine is dragging) and occasionally the right sliding door motor goes off when starting the engine. I'm thinking there is a wiring problem, but don't know where to look (or suggest to my mechanic to look). Also I notice a strange sound to the right in the engine compartment when I go over slight bumps in the road, could it be the motor mount? I had one replaced a year ago on that side, but possibly the other has gone bad. I had the front struts(?) replaced back in May of this year.
