Good day guy...so i have a 2007 mazda 3 with the ZY (1.5) engine.....all the car is doing is idling..no throttle response...and AT light on..also #1 & #4 injectors not firing..no signal to harness......car is electronic throttle.....i changed the ecu and same symptoms...i used a cable throttle brain and all the car did was solved the misfiring issue...but was idling very high...when i pressed the brakes the idle dropped regular...with the original ecu...the car goes back to to all the issues...but this time...only p2101-ff is showing and AT light on..i am looking for a wiring diagram but all i am getting is for the lc and l3 engines and not the zy..i changed throttle body...pedal sensors..crank and cam and no improvement...i live in the caribbean so our aftersales service suck
