Runs rough after warm up.
1986 GMC Sierra, 305, auto trans, carburated. Have read all the issues other
have posted, and it acts similar to the diaphragm issue, but not injected.
Changed fuel pump, installed inline filter, new gas, all the usual tuneup items,
still no joy. Could it be something in the coil?
