Mass Air Flow Sensor

[bobdimmm]

Hi All,

I have a 1998 Ranger XLT (4 cylinder). The check engine light is on and the dealership says I need a mass air flow sensor.


The engine 'pings' terribly in hot weather and the engine rpms do not drop fast between shifting gears (manual).


Are these symptoms of a bad mass air flow sensor?


Thank you for your help.

they could be.

do you have reason to doubt the dealership? if so, get a second opinion at a second shop.

Sounds to me like a dirty MAF. You could try cleaning it before replacing it. There is a write up in the tech library.

Hi Guys,


I appreciate your comments on my MAF sensor. I have always wondered why the engine had such a terrible ping.


Recently the fsst idle between shifting has become quite annoying.


I do not doubt the dealership but I do wonder if the ping and idle will be gone when the MAF is changed......I hope so.


Thanks Again,

Bob
