Help, throttle override by the ECU (not due to riding the brakes)

cossie1600 · 08-22-2011, 04:43 PM

it looks like i found the problem. it looks like a combination of three issues

#1 brake light switch (mine was out of adjustment, had to crawl under to adjust it), it was causing my cruise control to kick in and out when i first started.
#2 baffle plate broke inside my gas tank at 12000 miles
#3 here is the big one. the way nissan wires are put together in the tail light, you cant wire the trailer light kit like a normal car as the blinker light would trigger the brake override since trailer share the taillight with brakes and blinkers. the hesistation i experienced was actually the ecu shutting down the throttle on accel as the blinkers blinked. its the same reason why my car would mostly do it out of a turn and the mechanic didnt get it since he never used the blinkers. i have to modify my wiring harness to fix that. i cut the right side wire, so now i can use my right side blinker and not get hick up. yet as soon as i hit the left sife my theottle would go limp again.

with all that said. i have to apologize to nissan as this wasnt really an electrical bug caused by them. the dealerships still suck as now my alignment is all screwed up after they dropped my rear suspension to fix the gas tank. moral of the story, dont hack up or race the car.
