I had a similar problem - found that the injector was not leaking but the gaskets that seal the throttle body around the injector was.

Autozone has some kits that include all the gaskets and other items needed to rebuild the throttle body - it's not very difficult and if one gasket is bad, probably others are also. I also found that the fuel pressure regulator diaphram was rusted and flaking off into the throttle body fuel chambers. The kit will fix that also.

Good luck.

Bill
