Clear the codes and disconnect the battery for a little bit....That is wierd, IDK, I'll do some reading for ya though.

 

The only problems I've had with an IAC would cause rough idle and would sometimes kill the truck when it was idling, didn't have the problem under throttle.

 

2111 says to do the 29 point Pinpoint Test DV (2104 says to do the other codes)

Possible Causes of 2111:

• binding throttle body, stuck open
• TAC motor circuits are cross-wired
• TAC motor harness circuits are shorted together
• Damaged PCM

Have you tried cleaning the throttle body and the IAC? Also check for leaks around the MAF and TB in the intake. The rest of the DV test is all electrical pinpoint and would take forever for me to retype.

 

Get some contact cleaner and clean all the electrical plug under the hood around the TB. You can get TB cleaner and take a toothbrush and clean the TB really well then wife off... I am not a fan of cleaning the TB with the engine running as I don't want all the junk and carbon running through the engine... I like to run the vehicle to get it warm then manually clean the TB... Same with the MAF, spray MAF cleaner and let it dry... I just went through all this with my jeep chasing a running lean problem... TPS was 40 bux and didnt fix mine either... LoL... Turned out to be a glob of melted wired hidden behind the motor...

 

I did clean the throttle body and thought about doing the IAC as well by it started getting dark on me so I put it all back together.I guess i'll pull it back off and clean the IAC and maybe the MAF since it will be off too. Can you tell me where you got the 29 point test from, maybe I could use it for the electrical part. Thanks for your help, this one is starting to get too me.I did notice the butterfly stuck a little when opening it manually while cleaning. I assumed it was just from the electrical motor on the IAC.I'll have to look at it closer.

 

Normally the IAC would cause terrible idle and dying... Anything like that going on?

 

I've got an alldatadiy.com subscription, it should be in the Ford Service Manual as well.

 

TXOutlaw- It idles a little rough but only cause the battery was disconected and it needs to "relearn it's idle" so they say. I will try and clean the IAC tomorrow I hope and give another update.

 

so I cleaned the throttle body again and MAF and the IAC. The butterfly doesnt seem to be binding like it was. I put everything back together and I'm still getting the same code. P2104 and P2111. The fuse that was blown originaly is for the PCM memory. So I am assuming that by removing the battery cable to charge it, and not have that PCM back up memory power has cause a wierd issue. I checked continuity accross the PCM harnes and the plugs for the TPS and the IAC. I'm guessing now it's a PCM software issue. I'll have to have it towed on monday to the dealership. I think I have done as much as I can in my end. This is a nice surprise 1 week before Christmas. Guess I know what I am getting! Anyway, thank you guys all for your help with this one. I'll let you know how it turns out.

 

Well I just got the call from the dealership, it was the throttle body. Thank you guys so much for all the help. You kept me in the right direction!
