4 Wheel Drive/SUVs/different maf

Question
Hi.I have a '93 Ford Explorer w/4.0L V6.It started sputtering and idling rough. I pulled codes 157 & 158. I cleaned the maf but still got a code 157. So off to the junk yard I went. All the Explorers that were there already had their maf sensors pulled. So I pulled one from a Taurus with a 3.8L V6. It seems to run fine besides idling slightly rougher than it used to and I'm getting all clear codes. I haven't put a meter to it yet.Is it ok for me to use this maf?  

Answer
Ralaroco,

As I have stated, I'm not a mechanic by trade, and every vehicle has different codes.  You're pulling computer components from a different vehicle, so it's hard to say, how compatible the 2 maf's would be.  

I would check with a reputable shop, and see if they have a cross-reference book to see if the two units are interchangeable.

I do find it interesting that both codes came up.  Code 157 indicates that the MAF sensor is below minimum voltage, and code 158 shows that the MAF sensor is above minimum voltage.

You might have a shop check out the system with a higher end scanner.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you. Certified off-road instructor. I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles.

Experience

40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
