If you have a stock carb those things have a million vacuum lines and if they are old and stiff and cracked that can also affect it. also look at your intake gasket and maybe replace it. My car had similar problems and i replaced the vacuum lines and intake gasket and it runs and idles great. good luck

On many diesels, when I read codes they mention an egr valve, but what they are really talking about is the throttle actuator. What I don't understand is why you no longer have any codes. there are some codes which do not turn on the light on the dash because the computer hasn't decided yet that it is a hard code, so check for them anyway. The symptoms you are describing usually turn out to be either the throttle actuator, fuel rail pressure regulator, or a ripped turbo hose
Have the battery and alt tested for free at the local parts store. Tell them what it's doing, and start suspecting a fuel issue. Could be getting the right amount of fuel but not burning it. (plugs, wires, coil) Or could not be getting enough fuel.
Still hard to say, so get the charging/power system checked first. Let me know what you find out as I'm real curious now.
Same happened to a friend and it was the fuel pump.... Same for another friend and it was 2 bad coil packs.
Hi doesnt sound like anything major as long as it doesnt smoke bad or knock from the engine, it sounds like a decent service would help, try replacing the air filter, fuel filter, give it a decent oil change ( i use castrol magnetec in my part of the world), give the idle air control valve a good clean with mass airflow cleaner or similar. If thats dirty it may fix your problem when cleaned. The hot idle should be approx 500rpm and cold should be approx 1000rpm hope this helps
The ecs light is a check engine light, this is good, this way we can find the problem. you will need to get the codes out of the computer, and then define the codes, the code will be given in numbers by the lights flashes,this will help so much, if you can get codes i can help you define them and tell you how to go about fixing problem. to get the code you will need to open hood and near wipermotor you will see connectors, i have enclosed a diagram showing you the test connectors, connect the two together and then turn key on and count light flashes, the fisrt digit is in teenths and short flashes are ones, for example flash----flash-flash-flash-flash. would be 23, again f------f-f-f-f = 14. do this with warm engine, the codes will repeat after all codes are outif you make mistake turn key off and back on. get codes and i will help.
Has he checked the turbo, pressure? How is your air filter? could be a short to the coil for the pump Try running a couple of tanks of amsol additives cleaner, may just be carbon deposits forming on your injectors.
