Theres not really a lot which puts the light on apart from airmass sensor (common on 270) Crank sensor or a missfire on one of the pots due to a lead or two breaking down!

Theres the inlet port shut of motor near the starter, that would put the light on, massive loss of power to go with it!

i had similar issues, my code reader showed a misfire in cylinder 1, turned out to be faulty plug leads, most likely damaged 6 weeks earlier when i had a non MB service carried out on it as you need to pull the leads off a certain way to avoind damage.

you need to get the error codes read as SAM and TV already said, they will point youi in the right direction. I think if its the MAF, then disconnect it, if it runs worse, then the MAF was working fine
