My 99 toyota Rav4, with 110,000 miles, and v4 engine, has been shaking when I start the car. It feels like a little tremble. When I try to shift from park to drive it will sometimes stall. I also notice my gas mileage is decreasing. What could my problem be? Thanks
You may have a misfiring cylinder which could be caused by bad spark plug wire, plug, or intake air leak. Is the check engine light glowing? Reading the codes may move this from a general answer to a more specific one.
