Name is ***** *****. Have a 2005 Freestar 3.9. Has code

Customer Question
Customer: Name is ***** *****...
Customer: Name is ***** *****. Have a 2005 Freestar 3.9. Has code p0175. I have a scanner and get you any info needed. Vehicle recently had stuck secondary runners, replaced lower intake. The p0175 was there when the code for the secondary runner code was present, thought it might fix both, but only fixed the one problem. Cleaned MAF, checked all hoses/sprayed intake with carb spray. No change in rpm. EGR is clean and holds vacuum.
JA: Thanks. Can you give me any more details about your issue?
Customer: Has code p0175.. No other issues
JA: OK got it. Last thing — JustAnswer charges a fee (generally around $28) to post your type of question to Ford Experts (you only pay if satisfied). There are a couple customers ahead of you. Are you willing to wait a bit?
Customer: sure
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

Hi, my name is ***** ***** your scanner what are the LFT readings, on both banks?

Ask Your Own Ford Question
Customer reply replied 2 years ago
LTFTb1 is 5%
LTFTb2 is -10%
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 2 years ago

ok, then this is isolated to the bank 2, can you pull the plugson bank 2 and see if all 3 are wet or sooty, or is 2 good and only 1 wet or sooty?

Customer reply replied 2 years ago
4/5/6 all look normal. No wetness. Nothing discernable. Electrodes are reasonably clean.
Customer reply replied 2 years ago
All have a little bit of black.
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 2 years ago

ok, then you either have a bad MAF sensor, or the that bank exhaust has a restriction in it, the did you just clean the MAF or did you replace it?

Ask Your Own Ford Question
Customer reply replied 2 years ago
Cleaned it only.
Customer reply replied 2 years ago
Why wouldn't a bad MAF affect both banks though?
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 2 years ago

Usually it will effect both banks, but we have seen where the bank 2 runs rich also when they are bad, I would first have a exhaust back pressure test done on that bank, how many miles do you have on this?

Ask Your Own Ford Question
Customer reply replied 2 years ago
217k
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 2 years ago

then it is most likely a partially plugged cat on that bank, with that mileage, an exhaust backpressure test will verify this, the back pressure must not be higher than 1 psi at idle, if it is, then the cat is partially plugged,Tim

Ask Your Own Ford Question
Customer reply replied 2 years ago
After a long wait for a backpressure tester, there is less than 1psi backpressure. What is the testing procedure for the MAF?
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 2 years ago

the maf is checked with a scanner to read the airflow when idling

Ask Your Own Ford Question
Customer reply replied 2 years ago
That's not much help. What are good parameters?
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 2 years ago

at idle it should be around 5 grams a second, depending on your altitude,Tim

Ask Your Own Ford Question
Customer reply replied 2 years ago
4.98-5.8 @ idle..800 above sea level
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 2 years ago

then that test good, you m ight have a bad injector on that bank, if one sticks open, it can cause the whole bank to read rich, can you monitor the short term fuel trim, and then disconnect each injector, one by one, and see if 2 of them change the short term fuel trim, and one does not, if so, then the injector that did not change will be the culprit,Tim

Customer reply replied 2 years ago
With injectors all connected, ST is around -10.. it goes up to +14-17 with the outer 2 disconnected (1 at a time). Center one jumps to +44 when unplugged.
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 2 years ago

then it sounds like the outer 2 are the culprits,Tim

Ask Your Own Ford Question
Customer reply replied 2 years ago
But the rear ones do the same..
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 2 years ago

???? they should each drop it equally?

Ask Your Own Ford Question
Customer reply replied 2 years ago
The rears take the bank 1 stft to around 18. The front outer two take the bank 2 stft to 17 or so. The middle takes it to 44.
Customer reply replied 2 years ago
What should they be at?
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 2 years ago

ok, the bank 2 middle takes to 44? is this a positive or negative?

Ask Your Own Ford Question
Customer reply replied 2 years ago
Positive 44. The rest are 16-19 positive
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 2 years ago

ok, then my mistake, the center is the bad injector,Tim

Ask Your Own Ford Question
Customer reply replied 2 years ago
Should I test it or assume it's bad?
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 2 years ago

the easiest way to verify this, is to swap it with the enter one on the other side, and clear the codes, and see if the code come =s back a bank 1 rich code, if it does, then you know the injector is bad,Tim
