Re: question about injector insulators leaking

Ya it turns out I forgot to install the grommets between the rail and the injectors. without these there or maybe in your case, torn, the injectors press too far into the fuel rail. this causes the injectors to not press firmly into the intake manifold and causes a major vaccuum/boost leak. If those grommets are causing a bit of a vaccuum leak it shouldnt cause a rich misfire. Correct me if im wrong someone, but you would be running lean. Can you elaborate a bit on the problem? really when you let off the gas, your car should get fuel cut inorder to drop the rpms because the idle switch should be grounded. Unless your idle switch isnt adjusted right and its causing fuel to still be injected with not enough air for complete combustion. The idle switch is the single wire sensor that is located right on the back of the throttle body. Unplug it and test to make sure it gets ground when the gas pedal is not pressed at all. let me know what you find
