After further inspection today I determined that my cats are bad. Per instructions from another forum, i tapped on the cats with a hammer and heard the rattling of the honneycomb. I hadn't started the car yet so decided to start it up and drive it around the block. Idle was still rough but there was no sound. When I got on the road there was a ton of white smoke when I got on it which is not good. And as I pulled in the driveway the whistling started back. So there's just bad news all around, pretty much need a whole new exhaust and there is still something wrong with the engine. I guess at this point it is gonna be best for me to get the dealership involved and let them give me the bad news. I have a feeling fixing this car is going to cost much more than it is worth, which really sucks. I'll let you guys know what the verdict is hopefully tuesday, until then, thanks for the help.
