Ryan, How did it run before you put it for the winter. Test the connections to the warm up regulator. If it isn't functioning properly the control plunger will rise allowing to much fuel to go to the injectors. If it was running ok last year, then the 02 adjustment is most likely ok. John Hervey www.specialTauto.com << I have an 83' dmc w/ 19k miles. I tried to start it this spring and it would not fire. After replacing the coil and cleaning some connections, it fired up. But now it runs like the fuel line goes strait to the intake,extremly rich with large amount of white/ brownish smoke rolling out the exhaust, with a clear and black gas smelling liquid leaking out the exhaust. I got it to start a few times like this and it runs smooth at above 3000 rpm or so, but the lower the rpm the worse it runs, needless to say it won't come near an idle. I'm gussing this problem has some thing to do with the fuel pres. reg. but I am hoping to hear from some one that knows more about deloreans than I do. Thank Ryan >>
