My RX's ECU is displaying the following codes:
U0073: Control Module Comm. Bus Off
P0351: Ignition Coil 1, Circuit Malfunction
Just to make sure Ignition coil pack 1 wasn't faulty, i replaced it with a new one and still the same warning.
Since there is no Mazda dealership where i live, i would really really appreciate if you could guide me as to how to solve this issue or which part to replace.
Idling is quite rough & the 8 has lost some of its power. Should i even drive it?
