ET Missfireing up hills and under load

Post by Super XR6 »

got a problem thats pissing me off when i go up a hill in 5th like i do every day it starts to misfire and louses alot of power but when i drop back to third and thrasch it up the hill its fine, iv cleaned all the corosion off the ECU terminal and moved them around, replaced plugs and lead,

im now thinking that its the coil or the AFM

Sure is sounding like afm more than anything, and to do diagnosis, take the ecu out of its mounting spot, and on one side there is a screw thingy, turn clockwise and check in the little hole for a red and green led flashing. check on the bottom of the ecu for what each code means
