P1127 - h02's downstream sensors not tested

my car has no balls, it eats shit when i floor it, hooked it up to a scanner, doesnt misfire, fuel pressure is good even when driving it...this is the code that came up but before i had a code that said h02's swapped so i switched the wires and it went to the current P1127 code, i havent done any work to make this occur it just sort of happened one day, like i said it runs like a bag of ass i can feel it breaking up and it has no power... like i said again there was no misfire when running a diagnostic test...any ideas??

There was a time where one of my COPs wasn't even working, and no CEL lights came up. No codes, no nothing.

I'm thinkin its a misfire, or if the code that's given is right something wrong with the o2s

EDIT: I'm not sure, it says exhaust isn't hot enough, but o2s have heaters, and shouldn't throw a code while the car is cold. Maybe its just as simple as an o2 replacement. Does it sound like its running on less than 8 cylinders? Popping in exhaust at idle?

wouldnt i get a code on the scanner for a misfire though? and sorry if this is a dumb question but what are COP's? Also, it does pop at idle and doesnt feel like the power is there but not sure why.

Coil on plug. And when 2 of my COPs were out I didn't get a code, didn't say anything was wrong, even though it felt like molasses when driving. almost felt like something was holding it back, and it would buck really badly when in the throttle, exhaust sounded all weird too.

If you have recently disconnected your battery or reset your KAM (Keep Alive Memory) your car has to relearn what normal is and won't set a code for a misfire until it does.

This can take several days of normal driving before it completes it's "Drive Cycle."

If you haven't recently reset KAM or disconnected the battery and have made a repair or alteration to the vehicle, try letting it reset and then drive it. That way it will relearn how to operate normally.

i have had my battery on and off for a while now, and also i pulled a wire off the plug and it looked like it wasnt even touching the top of the plug... im not sure i will try to do some work to it tomorrow or this weekend and see whats up

You have wires on your 99+ Mustang? Do you mean that it looks like the Coils weren't touching the plugs?

oh and also i have a p0602 code which is a CTRL Module Programming code which is from when i swapped my motor, but after the swap i never had any problems until now, the motor i got was out of an 01 and my car is an 02 but i dont think this has anything to do with that.

I looked up that DTC on the Ford dealer only website for you. Here's what Ford says.

P0602 - Control Module Programming Error This Diagnostic Trouble Code (DTC) indicates programming error within Vehicle ID block (VID). VID data corrupted by the scan tool during VID reprogramming

Using the scan tool, reprogram the VID block.

If PCM does not allow reprogramming of the VID block, reflashing PCM will be required.

Looks like you need to take it in and get your PCM reflashed.

yeah thats what the scan tool told me, and also not really wires but the spring running from the coil to the plug

I'd start with the reflash before replacing any coils if I were you.

There may be some small differences in the way the engines run. Make sure that when you go in you tell them that you put a different engine in it.
