not a bad idea, just to make sure you can scratch it off the checklist

yeah hopefully something this simple is my problem.

Don't want to seem like the dark cloud here... but I'll be very surprised if the o2 fixes it. I can't figure out what's throwing my 1222 code either. Causes crappy idle issues upon initial start... usually about a minutes worth. Then she drives like a new car, engine only has 36,000 miles on it. Here's the list of what I've replaced so far:
1. ICV (replaced)
2. Vacuum Leaks (did TB heater delete and replaced hoses)
3. o2 Sensor (replaced)
4. Plugs & Wires (replaced as part of maintenance)
5. Fuel Injectors (mustang 19#)
6. Exhaust Header Gasket (had a leak)
7. AFM (replaced)
8. Engine Temp Sensor (replaced)
9. Throttle Position Sensor (replaced)
10. ECU (swapped known good)

Double post...

added the new O2 sensor and figured i might as well add a new icv. unplugged the battery and installed both items and 30 min later hooked everything back up. I started the car to let it idle and recalibrate and the ce light came up again (code 1222). I dont think there is anything else left to replace except my ecu. car still feels like its dumping more fuel than it needs. any ideas left?

To date this is the list of what was done:
new O2 sensor
new icv
new afm
new hoses and tb delete
new spark plugs and wires

i had a code in a ECU that seriously did not go away (even after removing battery power) until a tool reset it.
It was a similar code (main O2 sensor) from a spare ECU i bought off ebay.

Fuel pump?

nofear3544 · « **Reply #37 on:** December 05, 2008, 06:29:23 PM »

reset the ce light with a tool (peake search tool) and unhooked the battery.. no luck. Is there any way to spot a bad pump? i feel like the fuel pump is fine, in fact i think that the problem is too much fuel. I mean the light only comes one when traveling at a consistent rate of speed on the highway.

anyone ever seen a TPS wig out when driving on the highway like that?
that could be having x ammount of air going in and the TPS telling the ECU that y ammount is going in instead?
just noodling

any way to tell? i have been noticing that every once in a while i feel like the throttle sticks a little between shifts.

roundel318 · « **Reply #40 on:** December 07, 2008, 02:15:25 PM »

Well have you done a visual on the TB to make sure its working right mechanically?
Flipping it open and closed kinda quick with your thumb while watching it, about the speed of a high speed shift?

nofear3544 · « **Reply #41 on:** December 09, 2008, 07:54:26 AM »

i did mess around with it but i wasnt really sure what i was looking for. im going to pull it off again and replace the tb gaskets and also the switch i figured it couldnt hurt. ive already spent way too much money trying to fix this. I dont know if this helps at all either but when i start the car cold it makes a wine sound and it feels like the throttle sticks for a few seconds only on startup. then when shifting as soon as i depress the clutch the tack will stay at the current rpms for 1/2 a second before dropping (def more than normal you can feel a difference). I dont know if this helps at all but i figured more info cant hurt.

roundel318 · « **Reply #42 on:** December 10, 2008, 09:26:37 AM »

Interesting, do you have a broken spring on your TB assembly?
Definately a visual (DO IT WHILE ITS STILL REALLY COLD!!!!)
and might even lube your throttle cable a little, I did mine the other day and it moves better now when I push on the pedal, not as much hesistation.

nofear3544 · « **Reply #43 on:** December 10, 2008, 07:56:55 PM »

hmm ill def give it a look.

nofear3544 · « **Reply #44 on:** December 14, 2008, 02:46:20 PM »

So i decided to order new gaskets and take everything apart again to make sure i did everything correctly. I put it back together and installed a new tb switch. I started it up and she purred like a kitten but after idling steady for about five min the ce light came on again same code 1222. She's idling like a champ and pulling like a champ but im getting awful gas mileage and this code will not go away. What would be responsible for dumping too much fuel in the system. could my ecu be shot? Also could my timing be off slightly?
