Try this :
Disconnect the negative ( black ) battery cable ( 10mm open end wrench ).
Wait 10 minutes, connect it back up.
See if the CEL clears, it may not come back.
If so, then :
1. find the vacuum leak ( lots of ways to do that, use search )
2. clean the MAF sensor ( use search )
3. replace the MAF sensor.
You should be able to drive short distances, but don't take my word on that.
Find a good independent MB type shop that doesn't mind working on a Crossfire.
36 hrs passed by . Drove the car about 15 miles. Next day , 36 later, the check engi e light is back on. I also noticed a little shaking after I start tge engine. Its feels like the engine is close to shut down, but it does not.
i am thinking to check the Mav sensor but since I don't want to mess up anything I guess I need to get to a MB shop to let them figure out. Any opinions why it took 36 hrs for the check engine light to reappear???
