P0171 mean bank 1 is to lean P0174 means bank 2 is lean You did not state what engine you have but by your codes you must have the V6 4. Cleaned the mas and throttle body. To be honest, your message actually made me laugh. See: Some of the 1997 4. And also the fuel pump and the fuel lines or any restricted fuel filter. Most times when you get multiple lean codes you have a vacuum leak somewhere. I looked before I replaced the intake gasket, and didn't see anything, sprayed some carb cleaner around to see if it would stumble at all.
I am getting the following 4 codes in a 2003 Mazda Protege5 engine: P0090. I was very careful and meticulous, and made sure everything was lined up and torqued to spec. For example, I'm not entirely sure how to check for a vacuum leak although I know you have to spray something and see if it gets sucked in - I don't know where. After installing the new filter it is rock solid on 58 so I'm hoping that means the fuel pump is ok. It is also one of the most common. I took my Ranger to them one time when I was fighting an idle issue that wasn't throwing a code. Intake air temperature may come into play here too.
If there are any inaccuracies, or anything that you feel could improve the article, please feel free to comment or message. Is there a hose or series of hoses that connects the tank and the engine in some way for vapor or intake purposes? Every time that I have ever seen these two codes and only these two codes pop up at the same time it has always been a fuel related problem. Is it worth the hassle or should I just take it to somebody? If not clean it with some residue free cleaner. Hence why I came here asking, so I could direct my next steps. Reminds me of my job. It is the case, however, that the system does work by vacuum lines - the vapors are fed into the intake that way. We reset the codes and we'll see if they come back.
So I spent an entire Saturday replacing my intake manifold gaskets about 2 weeks ago. Consult your service manual for it's location if you need help. I let him know I used to be a lube etc technician for Ford. There are too many acronyms floating around the world today. In the future I will know that you got this. On those 2 codes, you have to do some testing to find out why there is a misfire.
I would say you need to get a fuel pressure test. This will cause you to get increasingly worse fuel mileage. I had the same codes 2 months ago. My problem also started shortly after installing new plugs. That's most likely your problem. When I accelerate, its fine, but when I let off the gas and roll it starts reving again causing the truck to shake. If this is correct, how much trouble is it to dop the tank? If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter.
They're guidelines released by a vehicle manufacturer and sent to dealer service departments worldwide. Two weeks later had the exact same problem with the same two codes. Gas fumes are not safe. That's what is giving the lean reading. I need to get them cleared up so I can get my inspection done.
Is that low enough to cause a lean code? I bought my elm327 of eBay from a guy from Brooklyn. Ignition coil burnt up again replaced this time no charge. It also throws the code P0171 to let you know that it has done this. The Ford one is a good one and rockauto. You could have a bad fuel pressure regulator. With the computer hooked up, if there is a specific cylinder s running lean, It should show up on the data report. Good luck figuring out what is wrong with your Ranger.
The engine is much quiter now and I don't have the shaking during deceleration anymore. So far I've check for vacuum leaks with ether. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. There are too many acronyms floating around the world today. The correction is stored in the fuel trim tables. The vapors are stored in a charcoal canister and fed to the engine to burn rather than going to the atmosphere. It seams as your fuel pump maybe weak.
