Hi All, I was searching the archives for the loss of power condition my D is experiencing and I found this: (cut from the original note by James LaLonde <krfds@xxxx>) "every morning when i start her for the first time, my delorean is a little hesitant. If I gun it or right when i let the clutch back out between gears she stutters and doesn't want to go. Also... nearly all the time, there are spurts when she's not as peppy- kinda just sluggish (like couldn't out-race a pinto kinda sluggish)." <end of cut> My car does the exact same thing. I don't think it's the fuel pump or ignition because both of those were replaced by PJ Grady in February. He did a full tune-up. I bought the car from Rob but I'd like to see if I can trouble shoot it myself because I'm sure he's tired of my phone calls. Although he'd never admit it. :) The condition is getting worse. I get passed by trucks up hills. After reading John hervey's response below I looked in the shop manuals for the "warm up regulator" and don't see any reference to one. Could he mean the "control pressure regulator"? While looking around I notice a wire that was dangling at the front of the engine (near the distributor -- I assume that's called the front). It has a white two prong plug with three wires going to it. A fairly heavy gauge black wire to one side and two lesser gauge black wires with blue stripes going to the other. After a long hard look I found what looks like it's mate tightly wire tied to a bundle of wires at the firewall. Do you think I should plug them together? They look like they've been apart for some time. I'm about to check my manuals to see if I can find out what they are all about. Any suggestions would be greatly appreciated.
