Oh I know this problem. What you have is a vacuum leak on the rear tube that exits the upper manifold. There is a little elbow on the back underside of the DOHC manifold, chances are it's loose because it's gotten oily and/or fallen off. This little rubber elbow controls your fuel pressure regulator and your EGR valve. Plus the vacuum leak makes it hard to keep the idle air control working to hold the vacuum keeping your car from idling rough. Put a small hose clamp on the elbow, careful not to cut it apart. Also the small red hoses may be coming out, insert them back in with a little gorilla glue on the sides as they tend to get loose with age.
