Air Flow Sensor May Fail at Higher Mileages on Toyota Tacoma

At higher mileages (125,000+) the mass air flow sensors may cause the vehicle to idle rough, run rich and even stall. It is recommended to replace the mass air flow sensor with a factory unit because the aftermarket units have very mixed results.

other mechanic has replaced two fuel pump and a coolent temp senser.I got problem and just saw it was idling ruff and hard start ,also it would stall when you try to excelerate.if you feathered gas it would slowly go up in rpm and thenbe fune at high rpm, so I cleaned throttle body used a whole can very very dirty . done many times on other cars never a problem. this time when starting wouldn't start had to jump battery and then it started reved it good then it just died no more start at all almost like no spark now did I fowl plugs? I think mass air flow is going out I cleaned with air canister but im clueless at this point any tips
