Anyone else running a redtop with E5 ecu? ok heres my problemo: O2 sensor is not connected because when i first did the swap i hooked the wrong brown wire to the o2 sensor, therefore no 12v(switched). ok now that i hoked to the correct brown wire it has 12v but then its start to stall when i lay off the gas and reapply; for like 1second and the feels like it stalls after every shift. I have the skinny O2. I think if I get the Fat O2 it will work since they share everything exept that.
