yes especially this truck the distributor shafts gets cracked and it moves the ignition timing. i always overhaul the distribuot when there is a problem. i replace the module, pick up coil and the mainshaft. also unplug egr valve because they will cause a lean misfire that will feel like a ignition skip.
