Last summer, with the help of the good people of this forum, I diagnosed and replaced a defective switchbox. All was well last fall and this spring, but last week the symptoms were back again. She runs like crap on 2 cylinders for the first 5-20 minutes of the day, then, all of a sudden she decides to run fine for the rest of the day. So I believe I have ANOTHER bad switch box.
My question is: Does anyone know of something else that may cause switchboxes to fail prematurely? Is there something else I should be replacing along with the switchbox?
