#56 of 99 1994 Ford Ranger 2.3L 5speed stalling
Mar 21, 2011 (6:34 pm)
I have a ranger with the 2.3L 8 plug, I have seen that many people with the same engine is having a stalling problem and so am I. I have change all the sensors except the pcm or the computer.
It runs great on the fwy or once you get going. its when you take off it wants to stall and you have to give it gas so that it wont turn off, at the same time when this happens i can see a small amount of black smoke and i give it gas so that it wont turn off, any hints or any successful repair that will take care of this problem

Been having some problems with rough idle and stalling while sitting still. Hasn't been running clean and smooth for quite a while and I couldn't find a problem.
A couple weeks ago just by chance I checked The "Mass Air Flow Sensor". That was it !! Problem solved now it's running like new again.
The mass Air Flow Sensor is located at the out end of your air filter cover. The thing is held in by two torques screws. Simply remove the two screws and remove it. It's a silver and black plastic box with a plug on the end of it. It's function is to sense the amount of air passing through it and send the information to the "Brain Box" which programs the fuel injection system with the right amount of air. Because it is on the clean air side of the air filter it can collect fibers from the filter itself, it also collects dust particles and pollen. When it is plugged up the brain box sends the wrong information to the fuel injectors resulting in a poor running truck. Here is a couple of hints to help you. Don't try to unplug the wire till you remove the unit. PUSH down on the plug release (don't pull) to remove the wires plugged into it. Here's the big one.....Use the right cleaner, buy a can of Mass Air Flow Injector cleaner and read the instructions on the can. It costs about $8 a can at O Reileys or Auto Zone. Let the sensor dry compleatly before you re-install it. After the first start the truck might throw a code (engine lite) If it does, no problem. Remove the negative wire from the battery, wait about 15 minuets then hook it back up. Re-set your clock start the truck and you're finished. Mass Air Flow Sensors should be cleaned everytime you change your air filter. It takes about 10 minuets total time and it's worth the effort. On the can of cleaner they claim 4-10 more horsepower at the wheels with a clean MAFsensor compared to a dirty one. Expect a smoother cleaner running engine also. 4-10 more horses also translates into fuel savings. This is a little job worth doing on any fuel injected vehicle not just the Rangers.
PS: My Ranger is a 2004 Edge with the small V-6. Yours may be slightly different. The MAF Sensor will be the first sensor in line on the out flow of your air breather box.

I should share a couple more things about the Mass Air Flow Sensor. First, On the metal side, the silver side, there are four small holes in the metal at different locations. Make sure you blow the cleaner thru the holes to make sure they are clean. Inspect the sensor an make sure you have cleaned all the inside vents and holes, there are inlets in front and both sides. Clean the inside of the plug also. Don't forget to clean the plug under the hood that plugs into the sensor. Put a rag under it while you spray to catch the overflow. That stuff will ignite on a hot engine.
Lastly check your exhaust pipe. Mine had a lot of soot built up on the tip of the pipe both inside and out, an obvious indication of an engine that is running rich ( to much ) fuel and and air mixture. Clean it up with a old rag and watch it for awhile The inside of the pipe should not be full of black built up soot, It should be kind of clean with a grey color inside.

try starting it and wiggeling the harness next to the under hood fuse block mine had rubbed against the bracket for the fuse block and had cut the power wire for the relay in to. it fixed my prob and no more swapping relays.

See my post re: mass air flow sensor. Sounds like what mine was doing. It never quit but It was running really rich making it run poor and die at stoplights and idled poor all the time. Eazy to fix, actually just clean it. Easy Easy Easy.

After lots of trail and error I found the cause to be the fuel air motor ( really not a motor but called one )got one for 10 bucks at salavge yard and now runs great .

Back to the drawing board .Engine ran great for about 200 miles and now starting the same ole stuff.It seems to be overloading on fuel.You drive it 55 and when you level out and let up on pedal it seems to start missing .If you keep adding fuel it will still go good but if you idle it may just quit .Start right back up but who wants that when Im sure it can be fixed Thanks JIM
