96 Lumina 3.1. MAP connector is just old, and brittle. I have ordered a new replacement aftermarket. The new one looks like it unsnaps to open. I am not sure if that is the case? I don't like butt splices, and this would be a very difficult thing to do where it is located.

 

 

Well, just a follow up. The connector I got isn't "keyed" the same as the sensor, so I bought one at autozone. My son told me there is a removal tool for these. I ended up with another guy soldering this one on, real fun that was!
