Try switching gas stations, or fuel grades; then try a thorough tune-up: replace the spark plugs, plug wires, fuel and air filters, and oxygen sensor, and clean the fuel injectors.
If that doesn't do it, replace your converter.
I'll check into what MB reccommends for the CLK 320 which is the engine in the Limited CF. Thanks and I'll try to run it but I'm in NY not TX so I'm cinda limited to streches of roads with police hiding around every turn.
There is sulfur in gasoline period, Canada allows more of it in gasoline than the US. Different gas companies have variations in the percentage of sulfur in their fuel. Crude oil has different amounts of sulfur in it depending on the source.
Your thorough tune up is expensive and a waste of money when done before the specified mileage or time unless a known problem exists and then only the faulty component(s) should be changed.
Changing fuel grades is limited to premium grade only and some stations only have one grade of it in their tanks.
You say you never run your engine over 3,500 and then tell us out cats are not up to temperature, if anyones cats are cold it's yours.
Replacing a converter can get expensive and need only to be done as a last resort.
What would you expect a Sea Foam tech to tell you except to use his product, I put his expertise alongside the mechanics you have spoken to and take their advise with a pinch of salt.
I suspect you have been reading a generic shop manual as well.
I would add nothing to my oil and gas as per the Crossfire manual instructions. If it's not in the oil and gas you do not need it in my opinion.
STP, Sea Foam and the like are generally a waste of money.
This shows how the hydraulic lifters work.
