Hi guys, I have a 1jz in my s14. Over the last few weeks I would get a completely random hesitation. The car would run super rich and then it would run fine. As I was driving around, the hesitation was just on and off. There would be long periods of time where it ran fine and then other days it would hesitate, I would let it sit and it would be fine the next morning. Then finally a couple of weeks ago, the car started running bad constantly. It would barely idle and was pouring white smoke and gas out of the exhaust. I checked all of my injectors with a noid light and 1 and 4 were bad. The light stayed on with the key on and when the car was cranked the light didn't pulse at all, the rest of the injectors were fine. So after doing some research I determined that it was the ecu. Apparently I had a bad 1-4 Injector driver. I immediately e-mailed Aaron of Driftmotion and he said it also sounded like my ecu. I decided to open it up and take a look but I did not see any leaking capacitors, the ecu looked perfect to me. But I sent out the ecu, got it back, and the problem was still there. Injectors 1 and 4 are just constantly dumping fuel. So I ended up buying another ecu the other day. It will be here tuesday and I will see if that fixes it.
I don't really know anything about ecu's but I guess when you send it in to get recapped, it doesn't matter if damage had already been done to an injector driver, then it can't be fixed?
But is there something else besides the ecu that can be causing injectors 1 and 4 to just constantly be staying open?
