Mass air flow sensor?????
hey guys im new trying to get some help first...
ok i have a 95 Ranger with a 4.0 in it ok when i drive it for about 30-45 minutes it will make a loud HUMMMING sound sounds like its coming from the MAFS but im not sure i know its not the air filter or anything so think its the MAFS? i also get bad gas mileage and it kinda "studders" when im driving sometimes
thanks
also it doesnt do it when its cold outside? and if i do have to replace it the cheapest i can get it is 230$ =/

Welcome to R-F!
Do you have a check engine light on? If so, take it to your local Autozone or Advance Auto Parts, they'll scan for free and tell you what's wrong.
Also, is it possible to record this humming sound and upload it on here? when a vehicle makes a humming sound, that's a broad statement but you've already narrowed it down to the engine so that's a start.
I'm with nbro, if the MAF was bad it would throw a code triggering the check engine light. -Mike-

ok i was wondering something if it is the IAC valve would it echo down through the intake pipe and sound like its coming out of the end? around the MAF? i mean it gets LOUD at the end by the MAF and filter
well pulled the IAC off the stuck my finger in one of the holes and i got a black gummy oil on my fingers? is that normal? i dont think it is how do i go about cleaning that? also the IAC valve is ony 60$
