Ok, so my d16z6 has a d16y8 head on it with the z6 camshaft and sprocket, and for some reason my stock d15b7 dizzy fit on the y8 head. I bolted it up, and my car started, but died after about 20 seconds. My dizzy cant be bad if it started up could it???? Any suggestions about why it stalls? Oh, and I also have the stock ecu hooked up, but people are telling me that it should run with the stock ecu. I dont know what the heck is wrong with it. Thanks, David
