My '04 F150 has a chirping, squeeking noise thats really difficult to describe. Only happens when in gear and break is on or driving in forward or reverse. At idle in park or neutral, its quiet. seems to be getting louder and i could smell something like burnt rubber or grinding metal in the cab. Also, just today, i accelerated from a stop and the engine reved up and then caught abruptly.. if anyone can help with this or has had a similar problem please gimme some guidance.. Thank you in advance!
