Well I wimped out and took it in the the shop. The mechanic tells me that injector 4 runs full open when hot. I'm really pissed off since I just paid $108 to have those 6 injectors gone over, given new O rings, bench tested etc. and now I'm not even confident that this injector place really did anything. What do you guys recommend? I feel I should have them at give me another replacement injector for free since I wasted time and money on installing injectors they told me were basically as good as new and obviously were not. Thoughts?
