Didn’t realize how much info I left out lol Yes whenever I tinker around with it I always reset computer to see if anything has changed.
it’s a 94 Auto. The stuff inside of the connectors is dielectric grease. So when I purchased vehicle from previous owner everything worked on the original cluster except for speedometer. When I first used Nissan data scan I never got a code for speed sensor. Back then the only codes were for vacuum leaks det sensor. After I got through emissions I didn’t see the cel for months. After a while it became troublesome driving without knowing how fast I’m going so I found a identical cluster from the junkyard that came off of a 93 auto. Once I installed it the speedometer worked but then I finally get code 14. At higher speeds when I take my foot off the gas it almost feels like the car is engine braking or dragging but then once I get back on the gas pedal it picks back up. It’s been this way since I got it.
