New guy , New question ? 3.0 mousing sound
I have a 99 Ranger that I use for a work vehicle . I just got it last week and I got a few problems that I just noticed . I washed the engine a few days ago and since I did that sometimes I get this deep tone howling noise from the engine , it comes and goes .. when gas is pushed it goes away , when you left off the gas you hear it . I noticed it doing this when sitting still as well . I never heard it before I hosed off the engine . I have no idea what it is !!
any ideas would be great
