Hello guys, My car is running slow when i gas it on the highway. I was thinking of changing my MAF sensor, But i don't see it anywhere. I called MB parts and they said the c32 doesn't use MAF, It something called the FLY?
Can anyone tell me where is the MAF located at on the C32?
This motor does not come equipped with one. It uses a MAP sensor in its place. You may be having an issue with the Intercooler pump. When this fails, the water in the Heat Exchanger will get hotter and cause the intake temps to rise to a point that the timing of the motor becomes pulled back to cut down power when knock has been detected, in order to preserve the motor. There are multiple options to resolve this, either replace the pump with another Bosch/Ford Lightning pump that sometimes last 30K or upgrade to the Johnson CM30/CM90. Also the best thing to keep the temp down consistently is to upgrade the Heat Exchanger.

Thanks for the info, i already replaced the IC pump with the MB original pump 3 weeks ago, its feels the same thing. i even replaced the radiator with nissens. its fast of take off but loss of power at 50mph+. any idea? should i upgrade the heat exchanger?
Where is the MAF on C32?
