1994 Mercedes-Benz SL320 Problems

Electrical Issues Due to Degraded Engine Wiring Harness

The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.

Hard/soft Tops May Develop Problems Due to Age

As vehicles age, various problems may develop with the hard and soft tops. If problems are encountered, it would be recommended to have a technician familiar with these tops perform the diagnoses.

Erratic Engine Operation and Poor Fuel Economy Due to Faulty Mass Air Flow Sensor

A faulty mass air flow (MAF) sensor can cause erratic/rough engine operation and fuel economy issues. Since this sensor measures the actual amount of air entering the motor, when it fails, the engine control module (ECM) takes the wrong information and delivers incorrect volumes of fuel to the cylinders.
