intermittent power loss
well after a few months of pretty good running my truck is back at the dealer. the tenth time this year. it seems every time i start it, it runs different. it'll run great on the way to work then on the way home it has no power til i get past 3/4 throttle. the next two days it runs great the next four days it runs like crap. and so on. truck seems like its bogging with a deep intake moan. disconnecting the egr seems to help. but then when i hook it back up it runs even better. for a day or two anyway then the same problems occur. i'm at 62000 miles running stock except for no cat. anyone got any ideas?
