Girl stang banger needs help with codes

[smokin00GT]

I have a thread in talk about my car titled "Welcome to the 500 HP club" I am getting some codes that I need suggestions on how to fix.
P0135 Heated O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
P0155 Heated O2 Sensor Heater Circuit Malfunction (Bank 2, Sensor 1)
P1507 Idle Air Control Underspeed Error
I changed the both of the o2 sensors at the dyno, and still got these codes. Can anyone help me figure out what's causing these so I can fix it?

135 and 155 could be a fuse 20A #8 under dash this is for a 2000 stang.

Wow dude you're awesome!!! Fuse was toasted!!! I'm gonna put in a new one now and see if it fixes it. Thanks a ton!!!

1507 Key ON Engine OFF: check voltage at IAC should be over 10.5
if so, then check resistance of IAC should be 6.0 - 13.0 Ohms
check resistance of both IAC Pins to case (individually) should be over 10,000ohms

Are there any bolts out there that are stronger than stage 8 locking? I fixed the fuse and did some WOT blasts around town, now my friggin header bolts are loose. I installed stage 8 locking bolts, but they have come loose. Damn.....I can't catch a break. It's something right after another with this car. I just want to enjoy it without something comming loose or throwing codes.

i've never heard of them coming loose before.

did the tabs break or the clips come off??

were the tabs rotated as far counterclockwise as you could get??

how are the exhaust gaskets??

When you are putting that much power and torque down you may as well get use to working on it alot, LOL.

now you need to find the reason the fuse blew.they don't blow for no reason

Most of the time it's the heater circuit in one of the 02 sensors that causes the fuse to blow. Since she already replaced them and then replaced the blown fuse she is probably fine now,

OK, I have inspected the headers. Here is what's up with them. I have an older set of ceramic JBA long tubes. They are a 2 Piece header on the driver's side. They were on the car when I bought it. The part where the 2 pieces connect is leaking. I tried some T bolt clamps to seal them up, but the clamps gave way. Now I have an appiontment to have them welded shut. If I had my way I would just buy a different set of headers, but they are expensive and a total pain in the ass to take off and put back on. The fuse has not blown again for the o2's so I think I am in the clear with that. Thanks for all of the input
