Default 94 Ranger 3.0 V6 OBD1 Code Reader

I recently replaced my 3.0 in my 94 Ranger with a Remanufactured Long Block (163000 miles). After it gets warm (45 minutes of highway driving) the Check Engine Light comes on. It will stay on for 30 seconds or so and then cycle on and off every 30 seconds or so. All of the Auto Parts stores here (Tupelo, MS) only read 97 and newer OBDII codes. Is there an Inexpensive way to read this code and determine what the code is actually meaning? I am guessing at this point that the O2 sensors are bad, since the light only shows up when the engine gets warm. I had the light come on after 4 hrs of driving 75-80MPH around 95000 miles, had the code read, and it said that the Passenger side O2 sensor was where the problem was, but since it was only after driving on a long fast trip, I chose to wait a while until they got worse. Any Suggestions?

Digital Ford Code Reader (1981 - 1995)

If you knew what code it was throwing I could look in my manual and tell you exactly what it was

Unfortunately man GM wins in simplicity of checking codes in the OBD1 system. Unless you know a dude with a modis or something. It sucks, but if you feel like getting crafty Youtube has an old instructional video of how to do it with the real equipment. You may be able to bridge terminals and get a code but I'm not exactly sure how it would manifest into a way you could read it. It a GM the check engine light would flash a determined number of times. On a ford i believe there are a few tests you can do in this fashion, but i think multiplr independent systems are all tied to the same check engine light. Good luck man.

I suggest you find a good backwater garage and let them drive it.
Or possibly pull out the phonebook and look for real small ads saying stuff like since 1982.(Garage ads) They may have an oldschool reader as most of their customers drive older hoopties, point in case. J/K

P.S. cycling is also prevalent on low oil pressure issues.

Look in the tech library for directions on checking with multimeter.
Checker Auto Parts, Schuck's Auto Supply, O'Reilly, Kragen Auto Parts and Murray's Discount Auto Stores, and most other auto parts stores have a cheap, (price) code reader, The one I got for my OBD1 cost $30 or less, comes with a manual that includes the codes.
If you are gonna keep the truck, spend the cash, it will save you $$ the first time you use it. Where I live, the mechanics charge $50 to pull the codes, then they won't tell what the code means.
