I have a BF XR6 and my
ECU is over heating is there away to fix this? The problem i have is the only error code that comes up is P0420 for the catalyst. I also just newly bought a trans coolant box. I issue's are it drives good cold but when it gets to a certain heat it jumps in and out of limp mode and when that starts happening i go to stop (brake) and the engine stops. I restart the car it idles good put it in drive and it cuts out again. I did a test waited till this happened again and poored cold water on the
ECU untill it was cold and the problem went away.
