So your car's Cel (Check machine Light) is on and you had the codes scanned at a local parts store. Your car has whether a P0171, P0174 lean fault code or both stored in the computer, these codes are based on Oxygen Sensor (O-2) readings. A lean code or codes indicate that there's too much oxygen in the exhaust. Remember parts shop have employees that have good intentions but they may not have the touch requisite to explain what the trouble codes really mean. These codes are based on oxygen measurements in the exhaust. A common mistake with lean codes is to replace the oxygen sensors. This could be a very high-priced mistake that will not fix the problem. Especially if both codes are present, because the chance of both O-2 sensors failing at the same time is very unlikely.
Most likely the cause is a vacuum leak. A vacuum leak can be caused from a vacuum hose, intake gasket or maybe even a leak in the air intake hose from the Maf (Mass Air Flow Sensor). Listen for a hissing sound that may lead you to the source of the problem. Some technicians will use a propane bottle with a hose attachment to help pinpoint vacuum leaks. With today's computers it's not quite as easy to check for vacuum leaks this way because the Ecu (Electronic operate Unit) will compensate quickly for the added fuel and a convert in idle is harder to notice. Oxygen sensor readings can be monitored with a scan tool while checking for leaks with propane, by finding for increased readings when enriching the mixture. Someone else way technicians can check for vacuum leaks is with a smoke test. By introducing smoke into a vacuum hose on the engine, the leak will be revealed when the smoke escapes from the question area.
Aftermarket air filters that use oil on the element can sometimes damage the Maf. Over oiling the air filter may allow some excess to get on the Maf sensor wire or element. This can alter the reading, fooling the Ecu into finding more or less air flow therefore changing the air/fuel composition incorrectly. I once worked on a car that would not start that had a question with a Maf. When finding at the wire in the Maf, there was a burned piece of trash that made it's way past the air filter. After cleaning the sensor the car ran perfectly. The ash that was on the Maf sensor wire was altering the reading by enriching the composition so much that the car could not run. After talking with the customer, he said the air filter was just changed. This was obviously when some trash got into the air intake hose that placed on the hot wire of the Maf.

Fuel Pressure could also cause a lean condition. If the fuel filter is clogged or the fuel pump pressure is low, there could be higher level of oxygen in the exhaust also. Most of the time though, the Ecu will compensate for the reduced fuel volume. So this is one of the least likely causes of a lean code.

You need an internet access and have to succeed a obvious procedure searching for auto repair manuals, but when you have done this procedure a few times it will be very easy to find the right instructions for do it yourself auto repair and it won't cost you a dime.
There are four types of automotive report documents that you will need to choose from when you want to do a repair;
General Manuals
In addition to some general manuals, most of these are related to the make. Here you can get step by step advice on how to repair most of the makes in the vehicle market. Let's say you have a Honda Acura 2002 model and you want to find a hand-operated for that make and model. What you do is perform the following crusade in a crusade engine: "free car manuals+Honda Acura+2002". Then you will have a long list of sites that contribute you with all kinds of descriptions for your Honda Acure 2002 model, and you can choose what you want.
Diagnosis descriptions
Automotive determination manuals can also be sub-divided by make and model. But it can also be divided by the area of the vehicle that is affected, for example motor intake problems, brake problems, cooling problems, exhaust problems, start or stall problems, transmission problems etc. Let's say you have a start problem. Your crusade would be "car determination manual+ start problem", then you should get more than adequate repair information to choose from. You can even get diagnostic trees where all options are covered for nothing.
You have probably more than one time heard some annoying noise from somewhere in your vehicle, without looking the source of it. This is one of the most kinky situations to run into because you don't know if it is a serious signal or just a small thing. Some websites gives you the opening to diagnose vehicle problems by the noise, sound and vibrating signals - and that is great. The sooner you find it the sooner you can fix it and then you can relax. When you search, you can spin the sound, for example "whine noise" or "shifter knocks" or "driveline vibration" plus car determination hand-operated plus ultimately the make.
Repair Manuals
In addition to regular manuals you can also get very instructive and detailed descriptions in other internet document or websites like articles, etc. The natural way to sub-divide such repairs before searching, is by the area of the vehicle that is going to be repaired, for instance body repair, exhaust repair, suspension fix, interior repair and even general car repair.
You do the crusade the same way as above; "car repair hand-operated (or description) + the area of repair and go straight through the list of resources you get.
Maintenance manuals
Though vehicle maintenance is closely related to your vehicle make and model, there are some maintenance issues that are pretty much base either you have a Cadillac, Vw or a Mercedes, for example changing oil, changing air filters, motor wash, fluid maintenance, tier maintenance etc. You can get access to maintenance descriptions by searching for the kind of maintenance plus "car maintenance hand-operated (or description)" plus ultimately your make and model.
I think you'll be amazed of the number of automotive repair free stuff online.

And all the dissimilar tales of intrigue and deception floating around out there concerning the universe of used auto parts doesn't positively help out at all in this regard, but rather makes the entire affair of obtaining the correct spare parts for one's car seem all that much more daunting.
One tool that vehicle owners will find to be much to their benefit and convenience while their hunt is a cross reference chart, which can supply you with quick and easy facts concerning models that will be a favorable fit for the part you need to replace. When it comes to replacing oil filters in particular-a part requiring periodic transfer that auto owners are well-advised to pay due attention to-the easiest way to go about the process is using a Fram oil filter cross reference chart.
Fram oil filters are well known for being both frugal and high performance, maintaining a sufficient balance between these two factors to make them the filter of choice of a great many car owners of dissimilar sorts. They have proven to not only be optimum in trapping dirt and other impurities in the oil circulating in your engine, but in retaining such particles for a principal number of time-all without reducing oil flow at all practically. Whereas the midpoint oil filter out there will only trap somewhere around 80% of the impurities circulating in your oil, with a Fram filter you'll be finding at in any place from 95% on up depending on which kind of stock that you get from them. So if your engine all of a sudden needs an oil filter transfer and you've never been smart sufficient to use a Fram filter before, you might as well conduct a Fram oil filter cross reference to see which products of theirs you'll be able to couple into your engine properly.
The favorable thing about a Fram oil filter cross reference is that you can hunt agreeing to a range of criteria, meaning that if you don't have all the principal facts you might still be able to find the correct replacement. You can scan the Fram oil filter cross reference charts by vehicle application (as they do furnish a wide gamut of products), through a quick hunt mode, or even agreeing to a competitor's parts number (to find the Fram equivalent). All of that means that when you get around to replacing your car's oil filter, you're approximately guaranteed to find a more-than-apt transfer through Fram.
Of course, you should remember that your oil filter's operation will always be conditioned by the conditions in which you control your vehicle and the kind of oil you use. With regards to the latter issue, it is always best advised to use purely synthetic engine oil of the top grade to make your filters last as long as possible.
