u can try an inj cleaning system but if its stuck u may have to repl it. does it have pwr pulse to it from electrical system?
There are temporary fixes available, but the permanent fix will be to replace the injector assembly. A GM dealer has a piece of equipment that will force nitrogen through the injector to "unstick" it, but it will usually happen again. GM had many problems with the injector design on your vehicle and most companies have updated the replacement injector to prevent the sticking.
