After finally getting time to fix this, I put a new regulator on this last weekend. The truck is still starting a little hard at times. The first two times it started real hard, but I thought it was because there was air in the line since I had pulled off the old regulator. It seemed to start Ok for me after I installed the new regulator, but the wife says it still starts hard at times. I'll have to be sure that I reattached that little vacuum line to the new regulator.
