45MPH going up small hills
2000 Chevrolet Tracker 1.6 stick shift* replaced fuel filter/air filter/gas cap. Removed EGR/ no carbon/all coils ohm 23/ terminals #2 & #5 12.37vdc to ground. I pulled codes 420,400,440 and 455. I know there are emission control issues but can not solve the loss of power problem. http://www.automotiveforums.com/vbulletin/images/icons/icon9.gif
