You have to tap the injector pretty aggressively while the car is running to get results. There is a youtube vid on it. If that doesnt work, then its probably toast. Try listening to the injector with a mechanic's stethoscope or a long screwdriver touching it and place the handle against your ear. Sound different than the rest? I really narrowed mine down by doing the temp test at the exhaust manifold. My number one cylinder was running 100 degrees cooler than the rest. In trying to track down the problem, I pulled the exhaust manifold off to have a small crack at the "Y" welded and noticed the #1 port was white ash color. Lean. Got a new set of injectors on ebay for around $120. Completely cured the problem. Symptoms were, rough idle with light "woofs" and random blasts of air out the tail pipe. Hesitation (bunny hopping) at all speeds, but worse at slower speeds. Also, revving in park up to 6K rpm sounded like the engine was coming apart. Good luck.
