Rough idle???
My name is Frank and I own a 2001 PSD F-350. I always plug in my block heater during the winter and sometimes even during the early spring.. On the few occasions that I've forgotten to plug it in, my truck will start up fine and idle without a problem...
however, within the past several weeks my truck will startup fine and idle for a few minutes then run really really rough I mean rough and then die. I then will try to restart it but then it takes a while to turnover. This does'nt happen when its been pluged in. Any thoughts or advice?
Thank You
