I'll have to look, when I put the car in reverse it misses and runs rough, and when the car is idle in drive it also does it.
I was thinking it was the cruise?

I have part which is top left hand corner of engine, I was looking at it and noticed it doesn't have a hose connected to it and figured it should have one, problem is .. I dont know what it is lol Here is a picture of what im talking about http://i37.tinypic.com/2ushn5u.jpg Anyone know what that is?...
