What is your question?
When it loses power I can press my gas and it has a popping noise and a little back fire. Have replaced the ecm check vac hoses and wiring and throttle body
What makes this problem better or worse?
When I accelarate

To diagnose this issue you will at least need a good scanner to get started. Checking for codes is the first thing. This could be few things and could be related to fuel delivery or ignition. If you don't work on your own car you can use this link to find a good shop near you. https://repairpal.com/repair-shops Alex
I have already checked fuel. Its not that. I do know when its acting up half the injecters stop working. Awd is off and traction control is off. I changed the ecm that did not work either
any help?
