    Yeah It didn't seem to change anything for me but I need to go back through and star washer all of them. I am getting a lean spike for a second after each shift but it could actually be tied to our grounding offset and not actually a true lean spike...ah Mod Hell how I love you.

    Take a wire brush to the lug and the surface.

    Put the star washer between the bolt head and the lug, not between the lug and the surface.

    Hmmm I sure will, hopefully this takes care of all of the anomalies that I have.

    Lean spikes between shifts seem pretty common. I don't pay enough attention to them to know if I get it or not. Still good to find more ground points to clean up.

    Yeah that is what I am reading/finding as well. Also my electrical gremlins tend to come out when the revs dip low (similar to shifting). Perhaps it has something to do with the voltage drop when the motor isn't spinning the alt. as fast?

    If you didn't have a 122, I'd recommend an 8" pulley

    Heads (and all the trimmings), and Cam are next on the list. Gotta beef up the valve train anyhow so I am figuring "while I'm in there"! Then perhaps I will look at getting the boost back up where it is now with an 8 rib setup including the 8" crank pulley.

    On a thread related note I spent the good part of 3 (back crunching) hours today locating and cleaning grounds. Preliminary results are good but I will wait a week or two before I say yes for sure and upload some more pics.

    Got these fixed! All I had to do was raise the Clutch in DFCO to 284*. Everything feels much nicer when I am getting back on the throttle now and when I push the clutch in it feels nicer.


    UPDATE:
    Spent about 3 hours the other day and finally got these high temps under control! I still can make them fluctuate with turning on/off accessories but only by a few degrees and not 20 like before.

    I ended up adding star washers to the following grounds as well as sanding the lug and area the lug attached to. (didn't sand the heads just cleaned them)

    Drivers side head rear.



    Passenger side head (both rear not pictured and the side facing the fender/battery pictured)



    The ground below the underhood fuse box.

    The first rule in ASIC design: GROUND IS NOT GROUND

    I had to Google ASIC (Application Specific Integrated Circuit) and I still don't know what the heck it is! I can share in the head banging though as these damn cars and their electrical gremlins can be frustrating. Although it wasn't all for not as I was able to clean up some wiring and route the evap and fuel line a bit cleaner and out of the way...

    What a great tribute to the Forums! Thank you to all for this information, i will be implementing it soon...I'm curious has anyone noticed that on a cold cold day, (key on, no start) the oil temp can be quite a bit below the actual or forcasted ambient temp? I wonder if this is related or just a weird attribute of oil? I'm in Texas, so I have only seen it on a rare morning here...

    I'd say its the correct temperature in that scenario. The engine would hold the cold from the night before and even though the ambient was now warmer it would read colder.

    The grounding offset issues take some driving time to show themselves.

    I figure it's just a bit of gauge inaccuracy. The oil temperature sending unit is optimized for measuring temperature well above freezing, whereas the external air temperature sending unit is optimized for measuring the typical range of air temperatures.

    A sump full of cold oil will warm slowly as the ambient temperature rises (so the oil temp will lag behind the air temp), but I've seen my oil temp indicating 3 or 4F lower than the air temp ever got. That's not a weird attribute of oil, that's just error in the indications.

    You'd get a better feel for accuracy by comparing oil temp to coolant temp right at startup.

    Check this thread for reference: http://www.cadillacforums.com/forums...connector.html

    I noticed the plug was loose during my clutch install. Slid it back in, but with all the work going on I forgot to secure it . Anyways, my oil temp has not gone above 210 (usually around 235 with light driving) and I'm up at least .5V.
