Hey guys, need a little help,
2002 2500 auto, no problems noted before truck sat for a week or so. noticed upon return that cruise boost in about 2-4 psi lower than normal, and egt, looks a little higher, specially upon shift into overdrive and acceleration to 65 mph or so, Egt can get to well over 1150 empty. I am able to boost up to 25 psi or so (hook), just overall numbers are lower. Only code found earlier was a 0122? the tps low voltage code. Any suggestions as for places to start looking for problems, can't find any apparent boost leak, bought a new Tps from Timbo, have not installed yet, batteries are original. any sensors to look at?
Thanks Pete
