The kick down cable is a mechanical connection that down shifts a transmission when the accelerator is wide open and the road speed is too low
as when going up a steep hill you have the throttle wide open and the vehicle needs to change down gears or the engine will stall
so no cable now down shift when required
run the fault codes as I would not think that the cable is the problem

Ok a couple things could be your problem here.
One: the cheapest way to start narrowing it down is Fuel filter.. its under the driver or passenger side front seats along the bottom.. if your not to savvy go to a auto parts place and ask them for help its a very cheap fix.
Two: Blazers are notorious for what they call a "fuel pressure regulator" failure. inside there is a little rubber bladder that eventually ruputures and will let raw gas into the intake manifold. depending on which engine you have W or TBI your able to replace the part itself. On the W engine you have the replace the whole Fuel injection CPI (central point injection) that's expensive 500 +.. and labor at a shop.
Three: The whole CPI needs to be replaced. Gm are idiots and use plastic tubes to connect to the fuel injectors which eventually like everything plastic on a car fail. and leak into the manifold. that would require a new fuel injection system which is Very expensive.
Four: Injectors needs cleaning or replacing. Eh cheap 40-60 dollar parts.. its a nozzle.. but the catch here is labor at the shop that's what drags the cat in.
Five: 02 sensor & plugs. Your 02 sensor will regulate the flow of air and gas based on what it senses and if its not functional it messes it up and you will encounter rough idle and surging.
Those are the most common thing i have experienced with my blazer and others. There are so many other things that come into play but those are the most common thing that happen to a blazer hope i was a help.

you have a single injector under the intake plenum it has 6 branching fuel leads off of this.A very common problem is the regulator attached to this and it leak off fuel which falls into the intake .causing this problem. it needs to be replaced .i have done at least 80 of these in my career.this will fix your problem.thanks for choosing fix ya

A vehicle that old will suffer from brittle and cracked vacuum lines. I would say there is a bad, or several bad lines leaking away vacuum from the intake manifold. Don't forget to check the hose going to the PCV on the valve cover. A vacuum leak will also cause the engine to stumble and miss intermittently when idling.

try the ignition module. if it is bad it does not send the signal for the the throttle body injectors to spray feul.

On the cable where it conects to the bracket is a plastic "C" clip. pull this clip up or out( depending on how it is situated now. Take the throttle on the carb to WIDE OPEN. hold it there and push the clip back in to hold the setting. Check the throttle linkage to assure you are getting WOT when you depress the foot feed to the floor. DO NOT DO THIS WITH THE ENGINE RUNNING. Running and engine at WOT with no load is BAD. Good luck glad I could help.
