i have a 07 mustang gt. i just installed the long tube mac headers from brenspeed. pain in the butt to put on with just ramps but now i get these codes P2004 and P2005. i tried to find as much information on here before i post but none really helped. the only thing i had bad problems with was the o2 sensors extensions werent long enough so we pulled the plastic coverr off soome from the factory o2's and they fit. and i drive it for a lil bit then tripped the codes. and brenspeed isnt open till tuesday and i need help. any information or help would be greatly appreciated! and also will it hurt my car to came driving it with the codes tripped?? thanks!

Have you gone through and checked exhaust for leaks? Or possibly wiring came loose somewhere in your engine compartment?Or it could be you just need a re-tune with the new headers. I dont know what the codes are though. How does it run?

P2004 (INTAKE MANIFOLD RUNNER CONTROL STUCK OPEN - BANK 1)
P2005 (INTAKE MANIFOLD RUNNER CONTROL STUCK OPEN - BANK 2)

Have you tried to clear the DTC's? The link below might give you a couple of things to check.

yea i have checked for leaks. dont seem to find any but im still going to exhaust shop to get the to weld the pipe from the headers to the prochamber h-pipe. car runs pretty good i guess. its not that loud either. its about the same as it was before the headers were on with the sound that is. feels a bit stronger when hitting the gas. appreciate the info the SACTOWN. i was thinking of clearing them and then see what happens.i am using the xcal2 and the tunes from brenspeed, but when i bought the headers i asked if i needed to have the tuner retune for the install of the headers and he told me no. its just weird that i didnt mess with any of that stuff and now theres a problem with it. Now do any of you guys know if this will hurt the engine if i keep driving it like it is? thanks again

well so far so good. i ended up having to delete the codes about 3 times and start it a couple. and now the engine light is off. hopefully for good! i really appreciate all the suggestions and help i got. THANKS!
