Hello,
First, I want to tell you that I am not from USA. I am from a small country in Europe called Latvia. So sorry if my English is a little bit bad.

Recently I bought a Mustang 2006 4.0 v6. I have it now for about 3 months, but all this time I’ve been trying to fix a problem with power loss, so I am here to seek help. When it's not working it feels like the engine doesn't have the right mixture and it doesn't work properly around 2500 rpms. To be honest its something weird that I have...

Loss of power, bad o2 sensors?
