It's a longer answer but there is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
The best way to test injectors is with an oscilloscope with a knowledge of good versus bad patterns but what you are looking for basically is longer on time as the engine RPM raises.

All you need is a noid light to check injector pulse. You can buy that at a harbour freight store or NAPA.
