Weird Whining sound when Revving/Accelerating
Hi everybody, i'm new to the forum but not new to forums in general. this place seems like a great Wealth of information and i'm glad to be a part of it now. a little bit of introducing, my names Mike, but you guys can just call me Novak. i'm 20, from pennsylvania and this isn't my first ford truck. we've had a couple since i was a youngin. the first one i remember is a 1986 ford ranger. then a couple ford explorers, and a 1994 f-150 ext cab. and now i have my own as a winter vehicle so i don't ruin my car in the winter here in pennsylvania. its a 1995 single cab with an 8 foot bed.
now lets get down to business. the motor is the straight six 4.9 liter hooked up to an auto tranny. the truck runs great, i just got done patching up the body for inspection and painting it and i pulled it out of the garage and took it for the first drive i ever took in it so far and it runs great but when you start to push down on the gas more than a little bit, it makes a loud whining sound and feels like its not getting the power it needs, at first i thought it might be the tranny but its not because i put it in park and revved it up and its still doing the same.... any ideas?
