Last week my car (1995 C-280) began to give me problems:
1. When I turn the car on the idle bounces anywhere from 4-14 RPM. When I put it on "D" everything is fine, however, when I come to a stop, the idle goes down and back up (it does this with and without the a/c).
2. When I step on the gas, the car waits about 2 seconds to respond, then it mis fires and finally accelerates poorly.
Both of these problems began at the same time. Any help will begreatly appreciated. Thanks in advance.
