[QUOTE="Gadametz, post: 747666, member: 10392"] I have a buggy that I've had a ton of power/ engine issues with. It has a 5.3/ th400/ np205. When crawling it has almost 0 power. It doesnt even have the power to pull the buggy up a hill or turn the tires at low rpm from a stop. If i get a rolling start and hit above 2k rpm's it has plenty of power and will go up anything. The entire fuel system is new except injector and maintains 62psi fuel pressure. Any ideas what is causing this? It has rockwells on 43's. When I say it loses power it literally won't turn them, and the engine wont rev any higher. It'll do a hard hill climb fine [/QUOTE]
