So your saying I should pull off the coil packs, wires and pluggs... Retighten all the header bolts to make sure there isn't a leak. Then check the pluggs and maybe replace them if there shot. Then put everything back on and try it again. That might work huh? How can i tell if the pluggs went bad??? What color would they be?

 

Have you checked to see if your drivers side header has burned through your o2 extension wires?If it did,fix it and check your Engine sensor fuse under the hood.It might need a new fuse.

 

Ok guys I installed my Hooker Longtube headers about 2 weeks ago and the car was fine til' 2 days ago. It started misfiring and it felt like it was coming in and out of power. SES light comes on and is flashing.... NOT GOOD!!!
I checked it with autozone and they say it pulls up these codes:
P0300 - multi misfire
P0132 - bad o2 sensor in banc one
So if replace the 02 sensor in my car and away went the problems after I reset the computer. Then the next day on my way to school it starts doing it again. AHHHH SOB!!! I couldn't be any more pissed about this situation. Can anyone offer some help. By the way I already tried all the little check ups on the engine like wires loose and check the coil packs to see that all the wires are all on properly. The funny part is that the car was leaking some exhaust from the header bolts not being on all the way tightened. So it tightened them then after i took it out for a drive that night in about 2 minutes all this crapp went wrong.... HELP PLEASE

 

Well, the loose header bolt most likely cause an exhaust leak, which REALLY pisses your O2's off. When the O2's are pissed, they obscure the fuel trims, and could possibly foul your spark plugs up. I'd atleast pull the plugs and inspect them for discoloration, and check all the bolts and flanges on your exhaust just to be sure there are no more leaks. O2's get expensive to replace!
