Hello I have a 1996 Ford taurus which through a code for a bad MAF sensor. I cleaned it and put it back in with the same code. I just Spent $103 on a brand new MAF and it still chuggs and stalls at idle. Also revs up upon start. Does anyone know what this could be????? PLEASE HELP!!!

Re: 1996 Ford Taurus Chugging MAF
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.
Did you buy a Ford MAF sensor? There are some brands that are not reliable or accurate. Buy a Ford MAF sensor, if your mechanic has decided that the MAF is faulty. You may have a leaking fuel injector, bad coolant temp sensor,bad oxygen sensor,dirty air filter, clogged exhaust system.

You don't change parts when you get a code. The codes are a starting point for diagnostic testing.
Codes are the symptoms of a possible problem,such as an out of range or defective sensor. Codes don't mean you change something. It's not that simple or are vehicles designed as such. You always test,then replace. You can't do either, if you don't know the system your working on.
The MAF and IAT Sensors are both in the MAF,one piece in most cases.
What are your issues ? Not likely a MAF gone bad.
Do you have the air filter cover on tight and no duct work leaks or vacuum leaks? That's what's possibly setting the code for the MAF.
A code P0174 may mean that one or more of the following has happened:
The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
There could be a vacuum leak downstream of the MAF sensor. and your solutions are.
In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
Inspect all vacuum and PCV hoses, replace if necessary
WHEN YOU HAVE MORE THAN ONE CODE YOU NEED TO KNOW WHAT IS THE PROBLEM .SO CHECK EVERY THING OIL COOLANT BATTEY AND GROUNDS. CLEAR CODE AND ROAD TEST NEED TO REACH OPERATING TEMPERATURE TO PROPERLY DIAGNOSE ANY DRIVABILITY .WHEN YOU DONE WORK ON THE FIRST CODE YOU COME UP WITH. WHEN YOU THING YOU FIXED OR REPLACED A PART GO BACK CLEAR CODE AND DO IT AGAIN IT YOU GOT THE SAME CODE YOU MISSED SOME THING. SOME OF THESE CODE YOU NEED A GOOD SCANNER .
The MAF (Mass Air Flow) sensor is located in the air inlet tube (air filter housing). You want to clean it, i am giving you a link that is perfect for MAF locating and cleaning.If it is completely out of performance, change it.If it requires cleaning, use electric parts cleaner spray. maf
