Try Changing out the Fuel Regulator! if that doesnt work then it probably is the Injectors, i have the same issue except now im getting fuel in my oil i got told to try checking the evaporator canister valve! so try that to if its open close it!

You have carbon in your New EGR! Dorman,Tomco and other after market Manufacturers make a replacement EGR gasket with a stainless screen to cure this problem!! Or you can get 2 EGR gaskets and a stainless faucet screen from a hardware store and make it yourself!!
Common problem on 4.3 GM engines!

Do you have a "Check Engine" light?

Check the coils in each cylinder. At 140k the valve cover gaskets tend to break and oil will fill the coils causing misfires and stalling.

It sounds like your EGR valve needs to be replaced. You can go to any auto parts store and get one. Try replacing spark plugs and plug wires also. If the timing was off it would pick up speed slowly and would vibrate really bad at idle. When you go to accelerate if it doesn't accelerate normally it may be the timing but i highly dought it. Try plugs and wires first. then the EGR valve.

1992 chevy corsica runs rough,stall or dies after stopping


Sounds the EGR valve and EVP sen is bad even if you tested it. The EGR valve cntrols idle and if carbon up will make the car stall or idle high and low (rpms going up and down) This was common on all cars during that time. I would say replace the EGR valve and senosr. This should take care of the problem. One more thing have the fuel pressure check on the car.

Only runs ruff during park and idle.


Your EGR valve shouldn't open up during idle or the engine will run rough and may even stall. Remove it and clean the plunger and port with a wire brush and some carb cleaner. Test the diaphragm with a vacuum pump. If it doesn't work after cleaning, or the diaphragm is bad, buy a new EGR valve.

It only idles ruff during park or idle


Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
