i just wanna make sure that im doing it right so i don't mess things up. first you take out negative clamp on battery and let it rest for about 15-20 minutes. after the 15-20 minutes are up, plug it back in and turn the car on and let it idle for around 15 minutes then u do a couple of hard runs to get the ecu going again...Tell me if i am missing anything???

The "hard runs" aren't necessary to "get the ECU going", but otherwise, that's the general procedure.

 

when u unplug the ecu.u should hit the brakes to fully drain the battery juice thats still in the car.

 

wait wait wut??? i have to press the brakes? i never knew this...im not taking out the ecu. im just unplugging the negative battery clamp and putting it back later. im not unplugging anything from the ecu

 

You have the right idea- Just take out the negative clamp for, oh I don't know. 5-10mins, plug it back in. ECU should be resetted. No need for hard runs.

 

thanks for the help. imuh go do it right now

 

u dont have to have it off for that long. 30sec is plenty long enough. imo i mean i have fixed my check engine light plenty of times by say fixing my o2 sensor and u just un hook power cable for about 30sec or so and hook it back up. that is it. done
