it sounds to me like you have a clogged cat. conv. if I had seen your post before Id have told you to ck hose to map sensor,ive found alot of this on hi mile or older cars,but I would drop the exhast at the manifold and drive it,if is ok cat is bad.as far as flushing the injectors go and buy a tank of top tier fuel and run it, you cannot disassemble an injector and flushing them generally is done thru the fuel rail schrader port.Maybe you should take it to someone who knows how to fix it instead of throwing parts at it,I work at a dealer and have for 18 years and Ive heard your story hundreds of times,theyve tryed everything and now I have to fix it.
