SL55 Low Power
Hello all, 2003 Sl55 40k miles.
Started engine yesterday, low coolant light comes on and goes off, check engine light come on and stays on. It idled fine, but when I try to accelerate engine revs extremely slow as if it has no power. I tried adding coolant, it took about a 1/4 of a gallon to fill. I still have the same results check engine light is still on and power is very low.
Does anyone know what the problem might be?
Thanks Joe

could be lots of things. Could be a headgasket went bad (rare) and is dumping coolant into the engine causing to to perform bad as well as run low on coolant. Could be when the coolant ran low the car is now not letting the supercharger engage. Either way you need to find out why you are low on coolant and as desired speeds said get the codes read for the check engine light.

That would certainly cause limp mode and power loss. A proper diagnosis should help to find your issue.
