Re: [DML] Re: Rough idle



Thank you! You're helping me narrow it down. I just replaced all of the
plugs, wires, cap, and rotor. I have no valve noise and I think there was
some work done on them a few thousand miles before I bought the car. The
car ran great before, but I shouldn't completely rule out timing. I think I
fixed my vacuum leaks, but again, I shouldn't rule it out. I'm thinking it
may be the injectors. I'm sure after over 20 years they're likely to have
some sort of build up in them. Although I don't exactly have money to spare
right now, my beloved DeLorean is worth it. It certainly wouldn't hurt to
have them cleaned or replaced.
