I have a r33 gts-t 94 model auto and have a stalling problem with it every so often, the engine turns of while driving i lose power steering have to come to a halt put it in park and restart it. I just changed all the plugs and the problem still happens i dont know much about cars but it has to be electrical. I hear some people talking about ecu what is this?. It can happen if i leave the car idle go inside then come back out to the car and it has stalled or after i give it abit of stick on the road any help on this would be appriciated. thanks
