my 05 lly has the edge juice and attitude monitor. everything was working fine till this am, i started it up and the egt alert went off and was reading 2100 degrees. it had sat over night in the garage and it was about 20 degrees out. the truck runs fine. the egt are all over the place. normal driving seems to bring the egt back down to normal range however at a stop the egt goes back up thru the roof. has anyone else experienced this problem???? could the pyrometer be bad??? please help.. i will be calling edge 1st thing monday morning for their advice.
