Glow Plug Light always on
Just drove my '02 PSD w/ auto tran through southern Ari/Cali. in pretty hot weather and a nasty rain storm. About 3 hours after the rain, my glow plug light came on and would not turn off. I called the dealer and asked if they had heard of this error before, and they gave me the normal run around but said that it may have something to do with some emission problem. The truck runs fine and I have no problems starting it. Any ideas out there? Please let me know if I should still be driving it or should bring it in ASAP.
