My pickup recently started idling rough, with a shudder. I put a new air filter on less than a month ago. After it started idling rough I put a new fuel filter and added an inline filter as well. I changed the spark plugs and the oil and filter at the same time as the air filter. The plug wires appear to be relativly new. What do you recommend?

Check the idle air control valve/throttle position and MAP sensor. And also check the fuel pressure
