I took it to the shop the mechanic said it was a bad oxygen sensor and a bad ERG valve I replaced both items and it still runs rough, he also said I need to change the camshaft position indecator sensor and the trans temp sensor, I bought all the parts on EBay but still need to change the latter two items.

engine still runs real rough and smokes black after it worms up to operating temp. and wants to stall.
also where is the cam sensor located at?

Your engine does not have a camshaft sensor just crankshaft sensor located on right rear engine.

Buy the engine mounts and transmission mount on your own and have them installed by someone you trust. Ask to see your old parts once the old one's have been replaced to make sure they were actually replaced (seriously). Once this is done you will notice a night and day difference in the sound and feel of your engine.
To reduce the black smoke use a fuel injection cleaner and pour it into a full tank of gas. The next time you have your oil changed, ask for a oil pan and engine cleaner (it should be poured in the engine run for a minute and then drained, then pour in new oil). You should notice a difference. I hope this helps you.
