i have a CEL that comes on after highway driving and off when rpms are near idle. so i want to clean the egr valve but i can't find it on my 93 sohc troop.

i also notice a smell coming from my exhaust. the smell is similar to gas but not quite. could this also be caused from a clogged egr?

along w/ the smell, there's a high pitched buzzing/whining noise coming from around the rear of the car....i can't really pinpoint where the source of the sound is but i think it's coming from the exhaust.

i would appreciate any help.
