Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello, I am Jose Sebastian. Your automotive expert, It's a pleasure to me to attend your question. Thank you very much for trust in just answer.
Have you done any leak test on the air admission system?
Dear customer, if you are checking for vacuum leakage, you replaced the sensors, you verified that there is no play in the manifold, the turbo is ok and the egr valve is ok, there must be a problem at the throttle body, it could also be a wiring problem but how weird it occurs only after going over 3500rpm then it could be a wiring or ecu problem. Could you tell me please how this happened?
Dear customer, as a general answer, I can tell you that it is likely that the problem is at the level of the electrical wiring that is not emitting signals correctly or the ecu is not giving power correctly.It may be not perceiving the signal or it is not coding it.This would happen over time.
