No that was the only time i touched the thing. I have 104,000 on her. now im getting the p0171 and p0172 Bank 1 codes. co worker said could be an air leak some where around MAF.

 

have you checked for a ruptured pcv elbow and where it connects to the intake.if you are getting a lean code for bank 1 & 2 then somewhere you are posibly getting unmetered air into your engine causeing a lean code.good luck

 

Ill inspect it today thanks..

 

lol, who do you work for Autozone or Advance Auto.

They don't tell you that they are recommending the part, they tell you "Sir, you need to replace the oxygen sensors". To a woman, or a man who has no idea how you just got that code, he's sitting dumb and happy. So he replaces 1 oxygen sensor on Bank 1, and takes it for a spin with a big S**t eatin' grin on his face that says "Ha, who needs a mechanic", but that doesn't fix it, so he replaces the one on Bank 2, that doesn't do it, so he decides to replace all 4. Now he's out $400 bucks for a FREE service and FREE advice from a $5 an hour "expert" that could have told him "Sir, you should check the PCV valve boots, or check for an air leak". Doesn't sound so FREE to me.

 

No I don't work at nor never have worked at one of those places. I'm an 8 year Journeyman Mechanic at a Ford Dealer. But it's a good idea for them 'cause it sells parts and that's what they're there for. We sell B-G brake fluid flushes that make our company money, but I would never spend $ on it myself nor recommend the service. Right or wrong, it's all about money, it's every where. I laugh at people who think that when a CEL is on they think all you do is read a code that tells you what part to replace. A code never tells you what part to replace, it just gives you an idea or an area to start looking for a problem. In this guys case he says he's got a p0171,p0172? In my 8 years as a Ford Mechanic I've never had a p0172 on a Ford vehicle. I don't even know what that is. I'm not saying that he doesn't have that code because it may exist, but I haven't seen it. He may be confusing it with a p0174 which is way more common. As another member mentioned before I would check the 2 hoses going into your air intake (next to the throttle body) If they fall out there will be unmetered air. And also very common is the PCV system to deteriorate at the pcv valve on the passenger valve cover and follow that hose with your hand to the rear of the engine with it running and listening for a hissing sound. The oily air that the engine sucks through the pcv valve causes the rubber hose to deteriorate and suck air.

 

bigsbetter - using your deductive reasoning strategy, its a good idea to go to an old retired geezers house and tell them that they need new windows throughout their house and it will save them thousands on their electric bill. We sell them windows, and it saves them nothing, but at least we sold them the windows and we are still in business.

We all know that the stealerships try to sell you parts that you don't need, and flushes that they don't do, or could do without, but it doesn't make it right. Simply stated, I don't like to see anyone get screwed. You don't go around smiling because you can sell a can of coke without the coke in it. You should be smiling when you do something honest, and that would be actually "recommending" while giving pros and cons of each.

Example:

Employee: Sir, it says that you have a lean condition on Bank1 P0171, lets take a step inside and have a look at our book and see what causes it.
Customer: ok, that would be nice
Employee: Let's see, it could be the oxygen sensor, a clogged fuel injector, EGR valve, leaking around the MAF, running the tank on E, or a vacuum leak.
Customer: Wow, it could be all of those thing? How much does that book cost?
Employee: $15.99
Customer: ok, I'll take it
Employee: sir, I would probably take a look around for a vacuum leak, looking closely at the PCV valve, and vacuum lines in and around the Throttle Body and then if I didn't find any, I would put some injector cleaner through it and see if that helps. If it doesn't, you could just replace the O2 sensor, but its a shot in the dark. It may or may not fix it. I would try the cheaper option first.
Customer: ok, thanks, I'll take the best fuel injector cleaner you have.
Employee: Sir, I recommend using the max mixture of cleaner to fuel that the bottle recommends. For instance if it treats from 8 to 20 gallons, put only 8 gallons in, and use the entire bottle.
Customer:Ok, I'll take 2 bottles of SeaFoam because I just filled up and probably have 20 gallons of gas. Man you have really been upfront with me, I'll definitely shop here again.

Customer goes away, and shops the store as long as the employee continues to be upfront with him. That is selling parts, and keeping customers happy.

 

You're right. It's wrong to screw people. But I still give AZ credit for the good idea. I give BG credit for coming up with a way to flush just about everything on your car, even though some / a lot of the services are silly. I guess what I'm trying to point out is that it makes me laugh when people do take their cars to autozone to have their check engine lights 'fixed'. But that's what uneducated do-it-yourselfers do. I can't imagine AZ telling you what part will fix your car. It seems as though they would say it might be this part or that part, and let the customer decide if they want to take a chance.

 

so bigsnotsobetter, who reads your codes for u, and how exactly does this relate to the 'ORIGINAL' post?????? What advice did u give?????? If u got nothin better 2 do, try making up to your wife.

 

What did I say to deserve all this criticism? I don't like to put people down nor talk bad about others, even if it is a business. Autozone is a reputable business. When I buy parts, I go to Carquest, but that doesn't mean AZ is not reputable, it's just what I prefer. My feelings were a little disturbed from that last comment towards me, unless I'm missing something, where did I deserve that?

 

I called my side mechanic that works for Ford he told me its probaly the PCV hose thats causing the problem ,He also got the same code readings as before . He will take it off and inspect it this weekend Ill keep everyone posted.

 

It was the PCV harnes. Dad and truck are doing fine now...Thanks everyone for your help!

 

lol, actually it was someone from the boards that told you that the first time.......lol. I guess I can see why he gave you such a hard time in posts above...

 

No that Smart A** gave me no advice and had the nerve to give me lip..lol i was told with those codes that it could of been a # of things so i took her to the dealer to get an oil change and while i had it there I had them check it out and they told me what the problem was...

 

Is this a joke? You've told about 15 different stories, was it the dealer, someone from the site, a coworker or an outside mechanic that fixed it?

I bet it sucks to be you, you've told so many lies, you forgot which one you told.

 

NO THE JOKES ON yoU a&& WYPE!
