05 silverado 170k just did wires and plugs ran fine after for a while. I had a code for air control mod so i changed it out truck drives for a short period of time then stalls out losses power. Will start back up but doesn't make it far. Took it to a guy he claims it's the ecm what would be the chances that's what's wrong with it?

Not many ECMs/PCMs fail. You need to have the codes read and post them here.

air control ? what are the codes ?

if no codes check fuel pressure procedure using a pressure gauge .

bad/low fuel pressure will cause this effect and no codes.
