1998 T444E tow truck keeps going into limp mode
trying to help a friend with a 1998 T444E international tow truck that after you run it for a few minutes it throws itself into limp mode and loses all power. The truck is flashed with powerhungry performance reflash as well but its set to stock power level at the moment. the dash shows a 333 fault code and when i scan it with the powerhungry fault scanner software i get MID 80 SPN A4 FMI 0A which as far as i can decipher is the 333 fault code. He has replaced the ICP, he also put a second ICP sensor in the other head and made a little extension harness just to deny or confirm that this sensor is the culprit. after that it didnt make a difference. the truck literally rolls coal even when on the stock setting when first running the truck.
i'll run through what it does more specifically. start the truck, pull out run out first gear it rolls coal but actually tries to get out of its own way. shift to second gear it starts to smoke again and about half way through the RPM range it it throws the light on the dash and loses all power. if i power cycle the key it goes back to normal till i try and run it even a little hard and right back into limp mode.
i have tried to use the live data part of the powerhungry software but it does not work right meaning it does not refresh fast enough to catch anything. i have tried to contact them about this but they dont answer me.
oh well, any ideas whats going and what i have to do to make this thing not go into limp mode? also bear with me, this is the first time i have ever worked on one of these.
