Hello everyone, reading the opinion of Ismael53, I remember a little common failure, which is especially given in engines with very groped wiring. In Nissan (KA24E, GA16de, E16E) I have seen what Ismael53 says, by mistake they changed the diversion or controllers of the injection, it seems to me that the 2 by 3, in these cases the engine did not walk even and raised or failed to accelerate. The other celebrated in these engines, is that after distributing them he was left with 1 cylinder off and salt bencina liquid by the exhaust, until the engine was heated, stopping benchin kliquida by the exhaust and leaving the cylinder without combustion, I also observe that the engine did not accelerate in cold as it normally does, at that time I do not associate it ... the first time I cost me a lot to give me the first time. What happened is that the injury connector was the same as the one of the auxiliary air valve (in charge of these systems of accelerating the engine while it is cold), it works with battery tension just like the injury, but the ECU Motor does not switch this signal, such as that of the injury, maintaining the permanently open injury until the engine takes temperature. The connectors are physically the same, but of different color, over time they are dismissed and added to dirt can induce this error ... I scanned it manually, I did not have codes, I came to think about a fault of the transistors that commute the signal of injection, testing the ECU in another equal car, it worked well ... After many tests analyzing the colors of the cables in the electric plane Citucion ... Change the connectors and immediately normalize. Greetings.
