My mirage has been sitting for a few days in hard rain.
Sputtering. on 2002 Mitsubishi Mirage

When I put it in reverse it was sputtering and knocking. What could be wrong? I am afraid to even drive it to get it fixed. It has about 98,000 miles and pray it isn't my timing belt. Advice please,from a senior woman. Thanks.
