Take your battery terminals off and clamp them together for a while, in the mtime that you wait split terminal blocks and clean out with electrical cleaner and put them back again. it worked on mine but if the problem persist i am sure someone will be able to assist.

SOURCE: Code #P0171 & code #P0174

The most common problem on a Ford with these codes is deteriorated PCV hoses. Check the hoses from the PCV valve to the intake manifold. Pay special attention to the rubber elbows. They often crack on the inside curve and the crack is hard to see.

You need to check for an intake leak, use a can of carb spray and spray around the top of the engine, if a leak is there the engine will change speed when you get near the leak with the spray.
Remember a sensor trouble code does not mean the part is bad, it means there is a problem with the signal from that sensor, it can be the sensor or the wiring to name a few. For instance a bad injector can give you a O2 sensor code.

The intake manifold gaskets need replacement as well as the o-rings inside - if you call FORD they should be able to get you the correct parts.

My 2002 ford explorer MAF don't get 12v it reads 3v what do i do to get it to 12v

Hi Ronald, I do not believe the Mass Air Flow Sensor is designed to operate on 12 volts, it usually operates on 5 volts or lower. I suggest looking at the crank and cam pick up sensors and making sure the MAF sensor is not damaged. A digital diagnosis should pin point the problem if it is not mechanical. Regards John

92 Ford Explorer XLT runs good for 15 minutes, then suddenly starts 'chugging,' loses power, and check engine light comes on.

Have the fault codes read again and get the code numbers so that we can identify if possible the causes for your problem. IN most codes recorded there are a list of possible causes for example if he said possible crank position sensor=== there is also the cam position sensor --wiring --ECM--HO2S sensor --MAF/MAP/VAF sensors that come into the equation

How do i chang worn rings?

im assuming you mean piston rings. to change your piston rings you need to remove spark plugs, empty your oil, remove your oil pan. unbolt your crank shaft and anything attached to it. at this point you should be able to pull your pistons down remove the rings and put new ones on as per the instructions provided with the new rings. use a hone or at least acid wash the cylinders before you reinstall your pistons. also make sure you reset your timing correctly. goodluck

My maf sensor pigtail was cut and stolen. I purchased a new pigtail from ford and I need to know the color codes so I can intall a new one. my vehicle is a 2004 ford f-150 lariat with a 5.4 liter engine....

As long as you are talking about the new body style ( 3V 5.4 L )

The module is the MAFS and the IAT sensors

The IAT section is :
PCM to IAT is Gray wire
The return to the electronic engine controls from the IAt is Gray w/ REd stripe wire

PCM to MAFS ( MAF ) is Light Blue w/ Red stripe wire
The MAF return on the PCM is Tan w/ Light Blue stripe wire
The ground ( same as the Charge motion control valve ) is Black w/ White stripe wire.

My 02 honda accord is loosing exsessive oil I have to pour a quart in every week. Don't see it on the ground or anywhere else. Not coming out of the tail pipe where did it go and how do i fix it.

what it probably is is you need new piston rings. the oil is splashed up from the crank case onto the bottom of the pistons, which keeps them lubricated. the piston rings are what seal the combustion chamber off from the crank case and when they go bad, oil gets into the combustion chamber and is burned.
