I bought a used 1988 Bronco and its a v8 and i have taken it to a ford dealership like five times cause stuff keeps going wrong with it but they act like they have no idea whats goin on everytime an that there is nothing wrong and then later they say oh well you have leaks and this and that but now that i have all that fixed i still have this same problem and they cant figure out whats wrong, you see i start it up and its roaring its like very powerful and then all of a sudden the little rpm gage starts goin down untl its below one and it seems like it wants to shoot back up to two rpm or three but it just goes back down again like its haveing a battle with itself and then once i start driving it when i get to a red light or something and its idle it starts making a weird humming/ whirling noise and its not good, but the ford dealership doesnt seem to have a cllue. what could it be
