[QUOTE="Gsteve, post: 1259205, member: 13255"] Im just looking for ideas or info so i know what to expect and so i can't have any wool pulled over my eyes. Heres all i can think of... - running perfect for 2 days - filled with 91 - trying to break it in properly , vary rpm , some wot , no lugging - on the highway in 10th at 60 mph and instantly start losing power. I pull over and slide it into neutral , its barely idling , near 350 rpm. I put it into first and its lurching and stumbling. I can barely get it moving , i leave in first and once i get to about 2,000 it no longer stumbles. As soon as it gets under 1,000 it starts again. Pulling away in first you're sure its going to stall and you baby it till 2,000ish. In 2nd i tried gassing it a bit and no power. It runs like a snow blower with the choke on full. Dealership says they looked quick and its not ecm or electrical..... [/QUOTE]
