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.
what would be the real failure
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!
car hard yo start. idles rough. stalls. starts, ame thing. after awhile it would stay running. drive it fely like it wants to stall. now is getting worse. this morning started ok ran it for 10 min. then shut it off. came back out tried to start wouldnt start. waited about 10 min. came out it started.
