I have a rough idle ( worse when cold). Also hesitation (worse when cold). If I remember correctly the truck is supposed to idle at 1000RPM till warmed up and after warmed up till your under 10MPH. My symptoms are it idles around 1200 till the truck has stopped. Then it idled down to 750rpm. Same for hot and cold.
I have checked and double cheacked for a vacuum leak. I have plugged all the vacuum lines at the intake manifold. I have used carb cleaner to try and find leaks. I have not done a smoke test yet. I have changed the spark plugs (set gap to .042"), plug wires, cap , rotor, and fuel filter.
I was next going to start testing sensors. First the mass air flow sensor. Anyone now the voltage parameters for the mass air flow sensor?
