Hi guys, the motor is in the engine bay and i got a 97 ex soch vtec wire harness for $50 from a jurkyard and I wired up everything myself, I follow color code and all wires and plugs fit perfectly until three plugs that were plug onto some plugs on the intake madifold, these wires have different colors, but they fit into the other plugs on the madifold (but I just not sure where each wire should be pluged and I did what I think seen to be right) for the ex wireharness, there are four plugs for the four injector and one extra, do you guys know where is this extra plug goes? anyways, I start the engine after wired everything up and the engine starts on the first try, but the noise coming from the engine is loud as hell, its not because I dont have the intake pipe to the throtle body and the exhaust down pipe is not connecting, the noise is coming from the engine. To my best knowlege, the engine make that kind of noise because the mixture of fuel and air are not equal, and also the header is hot as hell after 20 second from started the engine...anyone knows what went wrong??? could it be wires that pluged incorrectly? please help. thanks
