No Accelera Fors Fiesta 1.4 TDCI

Good afternoon .
I would like to help for a Ford Fiesta 1.4 TDCI of 2006, who on occasion when you make a stop in Semafaro Ect ... When it comes to accel to circulate the car does not accel and do not have to insist so that Accelere, please need to advise me to solve. Thank you first.

Hello .. I present a similar failure and the ECT sensor was varying very slow with respect to the actual motor temperature, the ect is replaced by an original one and the fault was solved, verifies your sensor and the real values ​​with a physical marker, remember that the ECT is important in the fuel injection.

Thank you, for responding so fast, I have been looking at the procedures and it is something complicated for me, since I am almost null in mechanics, I have been seeing and can also be the butterfly body? This morning to go to work, it was booting it and did not accase until it was gra one.

Good morning.
Take the car to the mechanic after personally cleaning the butterfly body and the EGR came out 3 failures. The EGR system, the potentiometer and the flow, after spending 160 euros in the flow rate the car now starts but recently started it costs it to accelerate ... I am already half crazy ... I do not have to do ,,,,,

It is very risky to change components without a previous diagnosis that indicates the origin of the fault, mainly the reasons for the lack or bad acceleration can be, in addition to the flower flow, the potential of the acceleration pedal, the connection and the communication wiring between both sensors, the first to measure is the continuity in the cable Continuity, once the good state of the communication is proven, the signal that reaches the MAF connector, (flow)
you put contact and look for one of the six pins (four thin and two thick) is measured in volts. Reach the indication of the potentiater of the pedal in failure.
