Mazda 2 - EAC code - louis14

Already 3 times I got the EAC code on my dashboard.At that moment my power level doesn't go above 10mph. When I stop the engine and I restart it the problem is fixed.

My dealer did a DTC(diagnostic?) reading of the computer in my engine but he could not recover the code. So he cannot find the cause of the problem.

He has done a software update of the PCM (power module).

What must I do?Will the update help the problem?

This has same engine and electronic throttle system as fitted to Fiesta models.I would get all the connector blocks to the engine checked.Also a low or poor condition battery can give this problem .hth
