Mercedes-Benz SL320 Problems

Rough running motor/lack of power due to failed ignition coil packs/spark plug resistors

Failed ignition coil packs or spark plug resistors can cause a rough running motor or lack of power.

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

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.

Repair Leaks From Head Gasket/Timing Cover Gasket Before Oil and Coolant Intermix

Internal and External engine oil & coolant leaks can develop from the head gasket and/or timing cover gasket; these leaks should be repaired before the engine oil and coolant intermix which can result in severe engine damage.
