I do try to let it warm up before I drive it.
At first I was not sure if it was normal or not, as I had never owned a car that did.
I was wondering if there was a way to defeat it, or trick the PCM.
My PowerStroke supposedly has non-adjustable fuel pressure, but I turned mine up with out putting a chip or tuner on it. I was wonering if anyone knew how the circut worked so I could get arround it that way... Like I did to my PSD.
