Irritated. Anyways, my map sensor has been giving me a fit lately on my 97 2.5l. Half of my sensors around the engine are from a yj due to my tj being a split year. Anyways, I recently replaced exhaust/intake manifold gaskets and when I went to hook everything back up the rig runs like crap intermittently. I've narrowed it down the the plug on my map sensor. I can wiggle it and it will either clear up and run fine or get worse. My question, since my map sensor has been discontinued, can I cut the factory pig tail and just wire in a new 3 pin flat style and then switch out the sensor with the matching 3 pin flat sensor? Attached is what my sensor and connector look like. The sensor is good but I can't find the pigtail by itself.... thanks.

You need NTK PN MA0135 according to some posts here on split 97 TJ's. Might take a look and see if thats correct.

That's the correct sensor, yes. However, my sensor is good. It's the connector that needs to be replaced and what I cannot find. I can find the flat pin connectors all day long which is why I'm trying to see if the flat pin sensor will work with my Jeep. I'll switch out it out with the new style and wire in the flat pin connector and be good to go. (Ideally)
 
If anybody cares to detail a bit the "split year" is a new one on me. Having a 95 and 91 YJ's and a 98 and 99 TJ's, and nothing made in 96. Is the early 97 a creature of its own with regard to some of the electrics and neither yj or late TJ sensors fit in some cases? In either case or early or late, Walker products offers either with the pig tale harness plug that you'd need to cut and butt splice in the wires. May not be the cheapest route but sometimes one has to do what one has to do. 22591001 for the YJ or 22591030 for the TJ. Those ore on Rockauto BTW.
 
@ItchyDong is spot on. Brake clean all that goop outta the connector and the sensor side also. Use dielectric around the rubber seal but not on the metal contacts. Cheap easy fix. If you can wiggle the connector and make it run better then the goop gotcha.

Try cleaning out the 4 pounds of dielectric grease with some contact cleaner. For the life of me I don’t understand how that stuff got the reputation for creating a better connection. It’s literally an insulator.

I don't like it either. Corrosion built up inside the pins before due to moisture getting in before. This was the "fix" lol.

Would you happen to have a link on the walker brand pigtail? I'm having trouble finding it..

Came into mention what @ItchyDong touched on. I used to make the mistake as well before I realized I was insulating the pins from making a better connection.

You want to use an electric connection cleaner. Please do not clean your connectors with brake cleaner (it will break down the plastic and rubber parts).

10-4 thank you! Will try this.

Would anyone happen to know what I could use to get down inside the female side of the connector? I could see a little bit of green corrosion/tarnish built up that I would like to get scraped out.

Depending on the hole size, I've used QD cleaner and a small pin or small paper clip.

D5DeoxIT is the best stuff I know about for chemically removing pin corrosion and protecting pins from future corrosion (it's amazing stuff, but I treat it like liquid gold due to how awesome it is and the cost).

Torch tip cleaner is a standard go-to. Be gentle and only use the size you need. Nobody likes a stretched out female… 🤔
