did mass air conversion now stalling vss?

It is possible. It's only two wires and you can get them from your cruise control module on the drivers side fire wall so it's worth hooking up.


*edit* I see you have an 84 so you may have to get a speed sensor from a newer car and hook it up that way.

Hooking it up solved my stoplight approach stalling.

I just did the same thing, the VSS is an 8 pin connector in the driver side kick panel. Don't go searching underneath the car, that can't tell you any thing. These signals are required for cruise control and as stated earlier, some have reported stalling problems on cars not equipped with cruise so avoid the head-ache and just do it. These will also generate an error code in the EEC if not installed. These signals come from a sensor that plugs into the transmission. The easiest place to tap into them is behind the driver's side kick panel. There is an 8 pin connector cable which runs back to the driver's seat, across the floor under the seat then back towards the front of the car and then goes through the transmission hump to the sensor. You will need to splice into the orange/yellow wire. The other end of this signal needs an EEC pin attached and this gets inserted into the EEC connector into position 6. You need to splice into the dark green/white wire for the other connection. The other end of this signal needs an EEC pin attached and this gets inserted into the EEC connector into position 3.
