i just installed some pacesetter headers in my truck but soon after my truck started to shake and would shift really hard does anyone know what this could be. i just changed one of my o2 sensors the one that was not reading anything and the hard shifting stopped and so did the shaking did i just answer my own question.lol

but really anyone ever encounter this problem before.

 

well once again guys thanks got the problem fixed changed the 02 and engine light went off.

 

Good to hear you got her running Jaime, I heard from Amadeo that it pulls awesome

 

yeah but there still more in her the tune is all over the place right now cause we could not get any o2 readings.
