Question C280 Runs Rough

Help! I have a 94 C280 with a rough running engine.

A few days ago, for no obvious reason, my engine began to run rough - both at idle and during normal hiway operation. The distinct odor of gasoline was present.

Research here suggested that the problem was likely faulty coil end caps, plugs or wires. I replced them all.

The result: No Change!

Could the problem be that I did not replace the inputs and caps that supply electricity to the coil? Or could the problem be related to a faulty sensor, orsomething entirely different?

There is NO check engine light and the only other obvious anomoly is that the A/C will shut down of its own accord, at slow speeds.

Thanks, in advance, for any insights.
