Car idle is rough Inspection $79.99 - $89.99 Get a Quote

Hello. Most of the time this is caused by a dirty throttle body. If it has some build up inside of it then this will occur. I usually start by checking the throttle body to see if there is a lot of debris in it. If it is clean then it can also be caused by a leaking intake manifold gasket. These commonly leak on this engine, especially when it is cold. I check this and I also check to see if the engine has good spark plugs and ignition coils.
