Ok, so here it goes... third hand to me I think? 07 700cc xp ranger. idles great, accelerates great to about mid rpms then when given more gas at peddle it boggs and no more, checked plugs they were black... sooty black. cleaned plugs and did code check..41 45 25. replaced tbap harness to good wire....cleared codes by removing neg wire at battery for 1/2 hr and ran again and same problem but no codes except for 25. ??????. I need help.... everything I have done was suggested by (local experts) and set new TPS to suggested setting according to members of this site for 07 700cc rangers. oh by the way new amazon injectors the blue ones.
