Tsuru 2002 Unstable acceleration

Hello everyone, I can help me with a 2002 tsuru at the time of accelerating above 1500 rpm begins to oscillate (similar to an IAC valve failure in idle) I already change the conbustible pump and the spark is fine, the problem is in the injection pulse and the ECU is tested in another vehicle without failure, if the carbure body accelerate and food Chief progress is fine, I wait for someone to occur or have notions of some correction of this failure, thanks and greetings.

How is the gasoline pressure? Despite having changed the pump, the regulator of gasoline pressure is failing. Cover The return of gasoline and look what happens. I hope you have also changed the fuel filter. Greetings.

Thank you for the interest, in fact if you cover the return to rule out the regulator and the failure continues, I suspect from the cable harness to the ECU, today I try it and let them know, greetings ..

I recommend that you check the MAP sensor of another unit that is working well since that failure occurs when the MAP is damaged and for your security of not buying this sensor in Valde do this test.

luck

These do not have a MAP sensor only MAF, but I already solved the problem, and it was that the temperature sensor sent an incorrect signal to the ECU probing that it would enter into protection mode, change the sensor and voila, it is worth mentioning that in many of the occasions it is not the sensor that is evil but the wiring, I recommend those who have a similar case check the reference voltage (5V) and the return of the signal, thank you very much. to those who invested time to help and greetings.
