Hello, After cleaning my fuel system about and replacing all the boots and hoses my DeLorean runs. But is idleing very rough. I belive that the firing order is off. Can someone give me the diagram on the firing order? ALso what are the three brass screws on the maifold right after the idle control. I would liek to thank you all for helping me with my car, and hope you guys have a nice thanksgiving. - Shain #10140
