Q: I have a 1997 Mazda Miata with an automatic transmission. I recently had new timing belt, pully and timing belt covers installed.

asked by on July 19, 2017

I recently had a new timingbelt, pully and timing belt covers installed. Now it wants to stall when I start it, stall in Drive and Reverse. It also has little power to get going in order to shift. It vibrates like crazy when I am stopped in Drive. My exhaust , muffle has gotten very loud.

My car has 154000 miles.
My car has an automatic transmission.

Hi there. One of the most common problems that occurs when major repairs is that often a minor component is disconnected and not properly installed. The symptoms you are describing are common with a vacuum leak. An engine requires a vacuum system to keep a constant pressure inside the motor to maintain a solid and consistent idle. When a vacuum line is not attached correctly or is damaged, it tends to cause the symptoms you are describing. It would be a good idea to have a different mechanic come to your location to complete a car shaking inspection so they can correctly diagnose this problem and recommend the right repairs.
