It is most likely the throttle position sensor i had the same problem it would get real loud and sound like a horn going off and after it goes off it drops to real low rpms and wants to die i replaced it and been running good sense also it is better off to get this in a junkyard it is only two screws holding it in if you buy it new it can cost around 40 to 50 dollars
