Message: [QUOTE="maplemale, post: 1137303, member: 17366"] Ya... they omh'd everything out and tested voltage out the GPCM and said all was normal. They cleaned the battery connections, said maybe I need new batteries and thought maybe the dirty terminals were causing an issue. They had no trouble starting it though at about 20 degrees. They thought it sounded normal too. I'm not sure I trust their opinion as a lot of 7.3 owners have rough idles and just think it's normal when it isn't. I grew up around 7.3s and it doesn't sound normal to me especially when cold and below 800 RPMs. Half the reason I had them test it was because I got a p0381 a few days prior. I saw it on the Torque app, but when I went to pull all codes a few days later with AutoEnginuity, it was gone. That's odd... cause I'm quit positive I did not clear that code in Torque. Unless Torque clears it automatically or is just buggy or something. I've always thought the truck was acting very much like glow plugs weren't working right. The GPs are new as is the GPCM. Only thing I didn't replace was the UVCH(s). Maybe I should just replace them anyway. Screw it... I think I will do that just to eliminate the possibility. Would rather put the money towards new up-pipes. Oh well... :cursing: [/QUOTE]
