Toyota 4Runner Problem Report
Toyota 4Runner Air flow sensor may fail at higher mileages
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.

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.
