94 3.4 auto i just dont know whats wrong with my car its seem to have lost power i got headersput on it its been a real drag with them on it everything sounds like it runnin fine no noises nothin i have no clue what would it be im gettin ready to put new headers gaskets on again and 02 sensers tommorow

 

it started doing it after you put headers on? did you make sure you plugged all sensors and what not in? and i dont know where EGR connects, but is that connected?

 

its been about 3 months, im still gettin my headers tightened every once in while but i have noiced that im usin more gas, my temp gets up to 220 sometimes and im barely pressin the pedal

 

hmm. i dont know much about that stuff, but if it originated with the headers, deffently go back over everything. double check EGR

is it throwing codes?

 

Punctuation makes it easier to read.
