It turns out that a number of years ago I replaced the map sensor pigtail connector because the clip broke on the original one. Well, the replacement I bought was a cheap aftermarket one and believe it or not, the 3 plastic “tubes” (that house the wire pins) were molded a little too long in length, causing the pins to not fully seat into the underside of the map sensor. I tried to grind down the tubes and then re-connecting it but it was still showing zero voltage.

This is actually excellent information, as it demonstrates how unreliable just taking an electrical reading off of a disconnected sensor can be. The connector and the harness are all as critical, and using a scanner and/or WinALDL to acquire readings when everything is connected is absolutely without doubt the superior method of checking to make sure that all sensors are functioning properly. Plus a scanner and/or WinALDL also displays the correct RPM. 
Kit, glad you got this all sorted out![This message has been edited by Patrick (edited 05-11-2025).]

Yes Patrick, I agree. I initially didn’t want to spend the cash on the Scantool but as you said it’s extremely helpful at diagnosing electrical sensor values and oddly enough it also pointed out that my tach was flat out lying to me. 🙁 Funny, I was thinking the other day about this song by the FIXX. (One thing leads to another)
That being said, as soon as I receive my tach board from EBay, I think I’ll start a new thread in the Tech section on replacing the old tach board with the new one. Kit

Just a follow up to in regard to fixing the root cause of my high idle. (poorly made aftermarket MAP pigtail connector)
Here is a pic for of what I did today. I installed (this time around) a factory GM pigtail connector and it worked just fine. As an FYI, I used to simply use butt connectors on connection’s like these but the last few years I decided to do the more proper thing and that is to solder the leads together and then cover them with shrink tubing. I had just soldered the connections when I took this pic. (shrink tubing was the next step.

I forgot to add that soldering wires on cars (in this case in my driveway) has gotten so much easier now that I have this. 😀
