Toyota 4Runner Air flow sensor may fail at higher mileages

(8 reports)
At higher mileages (125,000+) the Mass Air Flow Sensor may cause the vehicle to idle rough, run rich and even stall. Our technicians recommended to replace the Mass Air Flow Sensor with a factory unit because the aftermarket units have very mixed results.
Well mine is pretty much doing this I just got the heads and gaskets rebuilt. A few macs all told me it sounds like a cinser gone out. But yes u crank it it blows out a lil black smoke like its getting to much gas Like it's missing real bad but when u hit the gas it sounds fine u left off it dies. Can somebody please give me some pointers. I love my truck But damn I've put enph money in it -
