The LT1 in my 95 Caprice has an intermittent problem with how it runs. At times it will run great and have lots of power, other times it will run rough and looses power. It definitly feels like a cylinder is cutting out. If you are driving you can feel it all of a sudden have no power and run like crap, then the power just comes back like you hit the gas. The PO had his mechanic look at it and says an injector is going, how would I go about testing to find out which one? I was going to just pull one spark plug wire at a time, but its almost impossible to do this on this engine without getting burned.
