I've pulled the transmission twice but have yet to perform a tune-up beyond replacing the plugs, etc. That's lame, so now I'm attempting to perform my first real tune up on my DeLorean. I just need some help. :-) The diagnostic socket now works (thanks to Dave Delman; connection underneath was unplugged & damaged as you suggested). Dwell meter shows a steady position when cold, as it should. Unfortunately, once the car warms up, the dwell meter still shows a steady position. I tried running a ground from the ECU to the engine block as suggested here (http://mysite.verizon.net/vze7u0gn/id6.html), but it didn't help. I'm fairly certain I can hear the frequency valve buzzing. Now what do I do? Second piece of information to this puzzle: I started this quest because of a lean condition causing a "glug glug" noise on deceleration. Working blind since my dwell meter wasn't swinging back and forth, I dialed the mixture up 1/4 of a turn anyway. This fixed (!) the glug glug noise, but unfortunately caused the engine to begin surging up and down fairly significantly at idle - so I put the mixture back where it was. >From here, I have no idea where to go. Any advice would be greatly appreciated. -Ryan To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
