car running bad after header install When i was making my own o2 extensions i cut through all of the wires and i could have possibly mixed up the 2 brown wires. would this cause my car to run poorly? the car studders down low and shifting into a higher gear it feels like it falls on its face. 
If you think its your extensions just give them a look over but its more likely just and loose spark plug connection OR a cracked spark plug and the only way to tell is by pulling them out and making sure theirs no tiny lil cracks in the porcelian

yeah! my buddy is an electrician and even he said he wishes he didn't use the ones that came with the pacesetters . . . he said he's gonna buy the extensions from ws6store pretty soon

Did it run shitty as soon as you started it up or did it develop over time? If it did it as soon as you started it is something besides the O2's. If you want to be sure, pull the eng sen fuse and your car will go into limp mode and not use the O2's at all. If you are misfiring you should get a CEL, but it'd be a good thing to check the plugs anyway. Another thing to check is the ECT sender, I broke mine when installing headers and it made my car run like poop since it defauts to -40F or something like that.

ill go buy some extensions i guess if you guys really recomend them and then ill check the plugs i think it might be that one because i didnt think i pushed them in far enough
not necessarily, you can get just as good of a connection all you have to do is make sure the ends are clean and what i do is splice the wires in a Y shape then twist both Y's together and then wrap the two around eachother after that, then solder. Soldering will ensure a good connection and help from them coming apart.
