Heh - and give away all our trade secrets? ;-) We have seen this issue several times, and the smoking gun is that there isn't one. The strangest was one where the PO had wired the cold-start injector to fire all the time so that the car was fine cold and hot but would flood out warm (this acted like a stuck-closed thermo-time switch, but wasn't). These PO modifications are the hardest to diagnose because you just don't expect them, and they hide the wiring or plumbing modifications in interesting ways. Otherwise its often a combination of things, or something that's gone wrong and then been compesated for by changing something else. For example - the control regulator goes out of spec so the car idles poorly. Rather than replacing the defective CPR, the tech adjusts the fuel distributor CO. Then the car idles OK but is either too rich or lean everywhere else, which can lead to the problem (among others). This is just an example, and I've seen cars with multiple issues that you kind of peel back one at a time. This also makes it expensive to just start tossing parts at it based on suspicion and "what I saw last time", you really need to do your diagnosis with pressure guage, dwell meter, vacuum guage, eyes, nose, etc. . . The best explanation of how it's all supposed to work, and how to measure everything is (believe it or not) in the fuel injection section of the workshop manual and the technical manual. That's where the trade secrets are! --- In dmcnews@xxxxxxxxxxxxxxx, "Toby Peterson" <Toby@...> wrote: > > The majority of the DeLorean vendors are too buried in cars needing > attention right now to hover over the DML.
