      check your fuses, seriously, sounds like when my 16v that i drove for a year didn't have a good fuse for the isv and all the fine tweaking modules

      Have you checked and/or replaced all your ground wires? I know it seems minor, but I had an idling issue that drove me nuts for a month, and I fixed/ replaced a lot of what you did, then asked for help on the 'tex-- in the end it was a bad ground wire to the head.

      ^ Shotgun much?

      OP, second on the grounds and ecu. Having done everything else that you listed, the management was the next thing I thought of. I tend to not suspect the ecu and lean more toward brittle/broken wiring, but give it all the diagnostics to isolate the cause. Don't send that to a yard if you decide to let it go, sell it to someone else or part it. Hate to see a good one waste away in the boneyard.

      this is exactly what i'm not a fan of cis-motronic (though my audi 5k runs perfectly *knock on wood*)

      here are a few of my ideas (some may be far fetched)


      • vacuum leak (like everyone else said)
      • dead spot in your air box's potentiometer
      • tweaked hall sender window in dizzy
      • bad signal to ecu, bad signal to coil stage



      since you mentioned bumping the harness and a few seconds of decent idle... i'd not only trace the harness for continuity, but also measure resistance. most likely there's an issue with the wires between the fuel distributor and the ecu.

      it's a huge pain in the ass, because it's tedious work, but the one thing i've learned is to never trust a harness (even if you've built it yourself).

      years and years ago i had an 88 digi car (split year) that didn't match ANY wiring diagrams anywhere, and had some mysterious gremlin that i just couldn't track down for months. i replaced this and that and nothing made any difference.

      finally, while at my wit's end, i took a day and rebuilt the entire engine harness, reusing connectors, but rerunning and repining everything, and the gremlins were gone.

      EDIT: you can also bring it up to me in brooklyn for a few days and i'll get it sorted for you.

      Waterpump is about 4 years old. Alternator was swung down late last year. Oil was changed and has maybe 400 miles on it. Seafoamed as the same time. All the sensors are new.

      When I disconnect the ISV, it doesn't change anything. I just swapped the ISV out for another one since I have 12 volts going to it, I thought maybe it wasn't working correctly. Didn't change anything but this one at least vibrates like it should.

      Anyways, I don't think that'll fix your problem.

      If your fuel pressure is good, then seems like the timing may be off. Have you tried advancing/retarding it by moving the distributor?

      again, just throwing out my amateur 2 cents....
      I did try advancing and retarding the timing. Doesn't change a thing with the idle.

      But it all seriousness, don't quit on her. You'll find it. Try retarding the timing a hair.
      The only thing it has as far as cams go is a Euro intake cam.

      I hate to say that it is probably some crappy ground connection somewhere along the harness...
      Well, all the grounds for the engine harness are on the back of the valve cover. They are all there and all look good. I guess it wouldn't hurt to clean them again. Doing anything with the ISV doesn't change anything.

      So you feel like yours is ignition related? I just really don't have the patience to do a pinout on the ECU right now. I have a "new" harness coming tomorrow.

      Yes. No change. I thought maybe it was the chip in the ECU but the other one I have isn't chipped and didn't change anything.

      They are all good except for the one 30 amp fuse at the top. That is for the radiator fan after-run and well, it blows every time I put a fuse in it. Rad fan doesn't even work.

      I agree it does sound like a vac leak but I honestly cannot find one anywhere. I have sprayed carb cleaner, brake cleaner and starting fluid on everything and nothing changes. Maybe I shall order some new intake gaskets. Doesn't hurt to try.

      See above. I will clean them again in a few.

      3mm and yes, I have previously but the way the idle is right now makes it a pain to do since the reading bounces like crazy.

      I have another harness coming. I have this feeling that the wires to the CTS are ****ed up. Nothing changes when I disconnect it.

      I'm hoping that the harness I get will narrow things down a bit. Then I will tear that one apart and check it out.

      I would suggest pulling the entire harness from your bay and go wire by wire. Replace and re-pin as needed.

      ~25 year old copper wiring loses a lot of conductivity due to oxidation. It MAY have started out as oxygen-free copper (kind of doubt it..) but I highly doubt it is now.

      It will be replaced. Then once I get the new one in there I can hunt through that one. My back can't really handle leaning over the hood for a long time anymore.

      Lyme disease has done the same to me unfortunately.

      Well I guess that's what happens when you get older, grumpy, and aren't stupid enough to be in the car business anymore.

      I took the harness out. Cut most of the covering off around where I tapped it and it ran better. Didn't really see any issues with the wiring. The coil power stage harness was fixed when I installed that harness many years ago. Still all holding together. The DPR wires however are split at the connector. It is still connected and resistance isn't too bad. I have a feeling that this will be the end of it. Unless somebody has a good fuel distributor laying around that they want to sell cheap?

      to the yard.... just sign the title and I'll drive it over for you.

      Bad ground wires inside good-looking insulation?

      Have you checked the codes? Like how it tells you in the Bentley?
      I built a small black box with a light and button. Had very similar issues with mine and the code was always the hall effect sensor.
      Don't give up though.
