Ok so I have a 96 legacy motor and harness in my 86 brat and when I down shift and use the engine to slow it down it stalls when i come to a complete stop. Usually stalls long before it stops. it directly bypasses idle and just dies. Is this because I don't have the speed sensor hooked up? I didn't have this problem with the motor in my other Brat with the same engine and harness and the sensor was hooked up. Just wanna make sure if theres anything else i need to look into before I tear my Shelf out to connect it, I need to do it anyways so that my gas mileage will improve.

VSS and/or neutral switch

Ok thanks Gloyale. I'll get that hooked up soon then.
