Remove and clean the splash pan - a 10mm screw on each side. Look at the bottom of intercooler on the passenger side for a small hole. Also look on the splash pan for a 'clean spot' directly under the weep hole, before you clean it. It is easy enough to drill a 1 inch hole in the splash pan where the clean spot is.
If you are ambitious, remove the bottom IC pipe from the inter cooler and clean it. Given the age of the car, you may want to replace all of the IC flexible piping with silicone piping (about $100).
