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

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.

I just replaced the spark plugs on my 98 ford explorer suv 5.0. do i need to have the ignition retimed?

Wow! So many things can cause hesitation or miss. Did you run the OBD II scan? Auto-Zone will scan it for you. Usually on an older car,unless the spark plug wiring has been recently replaced,you need to do that too.
Then you have a lot of age on the coil pack also.Also clean your MAF sensor and your idle air control valve at the throttle gizmo.
Describe the hesitation a little more. don-ohio (:^)

OD light on 2002 ford explorer, delay between 1st and 2nd gear

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Hi, This could be a turbo related problem, or at worst a broken piston or oil ring! check the turbo out 1st, as if your talking about a ring everything & engine stripped down. Please send me feedback to Thanks Malcolm Campbell.

2002 ford explorer runs really ruff, when idoling and accelerating,

If it hasn't had the spark plugs and wiring changed within 60,000 miles,I'd change them out.
Clean the MAF sensor with brake spray cleaner also.Don't wipe the sensor wires,though.They're delicate.
If this is not the problem fixer,then check for `ye olde vacuume leake',which always is a good guess when idling poorly. don-ohio

My 2002 ford explorer engine stopped getting compression on one side. i was told that I now need a new engine. can the one side be repaired, or do i need a new engine?

That depends if the problem is with the rings or the valves or the head gasket.

Rings == engine

valves == valve job (remove both heads and take to a machine shop don't do just one)

Gasket == replace head gasket on that side.
