The engine hesitate on high velocity, and lost power also burned too much gas. I was told than the MAF was dirty, and I pull it out and clean it, but the service engine light stay on all the times.

Intermittenly at first: rough idling.stalling,black soot from the tail pipe, dying out coming to a stop,eventually would not maintain rpm's at idle. Replaced idle air control valve, fuel filter,fuel pressure regulator,throttle position sensor,fuel pump ( expensive and difficult as it is in-tank) I searched the internet everywhere for advice and never came across this :My shade-tree mechanic brother REMOVED the MAF sensor. Although it idled roughly, it did not die out,even took it for a short drive, which proved that the MAF sensor was faulty. Replaced it with a new one and I love my car again !Advice- remove the MAF sensor ,if idle improves,it most likely needs replaced.Cheap fix!
