Engine Computer Connector
My ECM has 2 connectors, a 14 way connector and a 60 way connector. The 14 way connector was compromised by techs prior to, or early in my ownership, probing the wire insulation. Eventually wire...

Well, I got around to getting some Deoxit inside the 14 and 60 way connectors.
That Caig DeOxit 'technicians kit' I acquired, came with these nice precision applicators/Qtips which fit perfectly into the sockets in the 14 way connector, and had even smaller ones in which the tip could reach perhaps half way into the 60 way connector, whose pins are smaller.
I first used the crc QED for the pressure wash, then q tips to clean and dry and buff pins. Then Deoxit Spray, on all 4 mating surfaces and let it sit.
The generic Q Tips I used to mop up excess and buff the 60 pin connector turned dark grey, I went through 4 Q Tips, both sides, and the pins turned shiny and silky oily smooth. The fifth q tip stayed pinkish with the deoxit.
The Caig kit provided mini q tips/precision applicators fit perfectly inside the 14 way connector sockets. The first one turned dark gray after the 4th socket and fell apart after the 10th and was dark black. The second one was medium grey by the time I got back to the first pin, and black by the time I finished the 14th. The third, light gray and still in excellent condition after cruising through all 14 sockets.
The 60 pin sockets turned the other, needle like swabs, black, even faster and I went through all the kit came with, but then started wrapping cotton from the generic t tips around the precision Caig needle sticks. Until I was fairly satisfied the smaller sockets were clean at least 3/4 the way deep.
I wound up using the last of these precision swabs to apply the DeOxit Gold, which they say is great for dissimilar metals. Which these connectors are.
The Q tips or swabs used with Deoxit gold stayed pretty clean, a light tan color and can be reused.
The connectors seated like butter. Dielectric grease sealed their perimeters after seating. Zip ties took all wire weight off both connectors. I cut a very thin hard Rubber wedge and used it in between the 14 ways connector's 2 halves.
Ran great to the ocean and even better back, but the code 53 is present again.
I doubt the Stalling issue is resolved and no doubt will come back at some point as the pins are loose and floating in the circuit board.
Anyway, anybody who ever used any other contact cleaner and thought it removed all contaminants, as well as oxidation, was wrong.
The amount of grey black crud I was able to remove with Deoxit after using CRC, twice, was amazing.
I have always used generous amounts of Dielectric grease on these connectors. These contacts were heavily oxidized despite its generous over application.
I am totally serious. I will be removing and cleaning each and every connector on my van with this stuff. And treating it with DeOxit Gold or Shield and Apply Dielectric grease after the connector is reseated. I really want to get inside my throttle position sensor and idle speed actuator motor, and 02 sensor connectors.
I want to get more of these precision Swabs. And the CRC QED cleaner or similar, as it is great for flushing and dissolving ugly old over applied dielectric grease and grime before getting the DeOxit on contacts and completing the job the CRC and dielectric grease alone, simply cannot.
