Based on your pics earlier i'm thinking you never cleaned the engine bay,is there any drought of any kind in your area,personaly a good start will be to get a couple cans of MAF cleaner and clean all the map sensors,iat,tb,cact,,anything that has a harness connector like the spark plug connectors,they get all kinds of dirt and oil buildup overtime,you mentioned you changed the plugs,did you also change the boots on the coils? only a suggestion cause every little bit helps.

It's good to clean the map sensors every once in a while but it's very abnormal for your O2 sensor to flatline in the log....that almost has to be a component failure

What do i have to say to ford for them to plug it in for a test drive and monitor to see if the engine is running correctly id be willing to pay a few hundreds bucks if it led to some warranty repairs. shouldnt my 02 sensor going give me a code? seems like these cars dont like to tell us anything...

I really don't know why it wouldn't throw a dtc....I've never seen an instance where the O2 sensor stopped reading...the primary O2 sensors give feedback in open and closed loop in these cars so there is no good reason for it to do what yours did....might be kinda tough to get dealer to do anything without a dtc

i really should just trade this thing in lol

I would try to say that your experiencing poor mpg and maybe they would consider hooking it up to the IDS software and take it from there,sounds like you have not visited the dealer in a while,if so maybe you need to reprogram your PCM,maybe theres an update revision available,just a thought. Z

i bring it in all the time they never say anything about updates it has been updated a few years ago but im just sort of getting stacked with problems with this car. changed oil frequently with pennzoil platinum, mobil1 or motorcraft full synth. got tranny ptu and rdu fluids switched out a few thousand miles back.

Have you sent the configuration file to Torrie,maybe he can give you a little input on whats actually going or any ideas. Z

curry67 · August 03, 2015, 12:50:14 PM

Yes, MAF cleaner is fine for MAP sensors & pretty much any electronics. Yes, place part on scott towel and spray away. Should all evaporate. Make sure you do this in a well-ventilated area. Not sure about your question about the "MAF leave in tube" ...

ZSHO · August 03, 2015, 02:33:34 PM

I would spray the sensors on both sides,the one by your air filter just twist it off gently and spray both sides of the electrodes and let them dry for a few min,also (dont)use the straw cause you could damage the electrodes,while your there clean the connectors also,best of luck to you and keep us updated.

Do i have to detach the sensors fully?

If your refering to the IAT sensor,the one by your air filter the answer is no,but personaly i always like to remove it. Z
