OK, I dont know much of anything about Honda's. I have a 1998 Mustang Cobra, and can work on that with my eyes closed almost. My younger sister had an 89 Civic Hatchback DX. Well her engine blew and she got an engine from Japan, I "think" out of a 91 CRX SI, but I have no idea what it is, top just says 16 Valve, which means to me DOHC. She says they told her that it is a SOHC ZC engine, she got it from NipponMotors???? She had some "friends" swap out the engine, and the ECU. They had the car for about 6 months before she gave up and bought a new car. Well now her old car is sitting in my yard, I would like to get it running to save miles on my Cobra and have some fun with it. It will start and you can drive it, and has nice power. But it lurches and surges, and whistles at the intake, does not really want to idle... The only way it will not surge, is if you are full throttle, its smooth then, sounds supercharged cause of the whistle though, but aggrivating. When driving, the engine is either on the throttle or off the throttle, you cant hold a constant speed like cruizing, jerks on and off the throttle if you try to do that. If I turn on the key and count the light in the passenger floorboard, it repeats these numbers, 3,5,14,16,20. THere are hoses coming off the Intake with bolts in them, where do these go? or do they matter?? I cant find a diagram or anything of them.... Any ideas where to start here???? THanks a bunch!
