Check Engine Light on after filled up with gas?
I have 99 ML 320. We purchased it about 2.5 years ago. We have never had any problems. This baby has been "purring".
I have ALWAYS used Supreme gas as recommedned. We normally go to Chevron.
Today I went to fill up at Chevron as normal. I definitely used Supreme (91). As soon as I turned the car back on though, it shook a little and then jumped and the check engine light came on. It didn't go off, so I drove it right home. I turned the car off, and then turned it on again, to see if it would go off, and it didn't. Then I revved the engine and the car really started to shake.
Could it be the gas? Perhaps they had the wrong gas in the Supreme line?
It seems weired that as soon as I filled up this happened. Again, this car has had no mechanical problems or tell tell signs that maybe it may break down. I talked to a buddy of mine who said his Benz (E320) for some reason doesn't like Chevron gas, and the first time he used it his car wouldn't start. Another used regular gas and his car turned into a "putt putt"
What should I do? Am I stuck with going to the mechanic and paying for a diagnostic check? Is there anything else I can do?
