4.0 swap and check engine light
Ok, I've got another check engine light question. When I put the 4.0 head and EFI on my CJ, I put a small cel in my dash. I'ts never worked. The light is good, I just took it out and tested it. The power conection from the computer and the ground conection seems to be good. Will the cel only blink if there is a problem, or should it come on when I turn on the key until the motor starts, and should it come on if the engine dies? I've tried the on/off 3x trick, but it still doesn't work. It's the only mystery left for me to figure out on the swap!
