With no load on the engine, i can rev it (only went to 5K, I don't really want to rev it any more than that). Once i put it in gear and try to drive it it has no power, i can get it moving but as if it has a 50hp eninge in it. So i checked the obvious, TPS is OK, MAF is OK, i have a spark on all plugs. I don't think it's a fuel issue since i can rev it with no hesitations when the engine has no load. I'm not sure how i would even check if it was a fuel issue. The only thing i can think of is a vacuum leak when the engine is torqued when trying to move. I need to get out there with a propane source to sniff that out too. Do you guys have any other ideas as to what might be wrong. I'm at a loss at the moment and not sure how else to trouble shoot. Thanks in advance.
