Yes.  Next to the ash tray there is a black slide off plate that reveals the OBD I plug.  {1996 and newer can be read with an OBD II reader (read for free at Advance auto or Auto Zone)}  Once you reveal this plug on the 1995, you can plug in a single jumper wire (or even a paper clip) in the #4 and #15 pin hole.  There are two rows of pin holes, count from the upper right to the #4, then on to #15 (which will be the second to last pin hole).  Turn the ignition switch on (motor not running), insert the jumper wire for about 3 to 5 seconds, then remove the wire.  The ENGINE LIGHT will flash a hold, then the code, which will go something like this, flash, flash, PAUSE, flash, flash, PAUSE, flash, PAUSE, flash, flash, flash, flash.  Then it will repeat the codes if you just sit there and observe it.  The code in my example would be a 2214 code.
Below are some code I found on a website.  I hope this helps.  Now I ask that you take the time to answer someone elses question.  Lets all share.  Good luck, "Peace through power and knowledge"

Since this is an intermittent problem, first try to determine if the problem arises due to one of these many intermittent problems:

* Vehicle vibration
* Heat sensitive
* Freezing
* Water intrusion
* Electrical load
* Cold or hot start up

If you can't isolate the cause of the intermittent problem, you can try adjusting the Idle Speed/Ignition Timing/Idle Mixture Ratio:

Idle Speed/Ignition Timing/Idle Mixture Ratio Adjustment

PREPARATION
1) Make sure that the following parts are in good order.

* Battery
* Ignition system
* Engine oil and coolant levels
* Fuses
* ECM harness connector
* Vacuum hoses
* Air intake system
* (Oil filler cap, oil level gauge, etc.)
* Fuel pressure
* Engine compression
* EGR valve operation (If so equipped)
* Throttle valve
* Evaporative emission system

2) On air conditioner equipped models, checks should be carried out while the air conditioner is OFF.
3) On automatic transmission equipped models, when checking idle rpm, ignition timing and mixture ratio,
checks should be carried out while shift lever is in “N” position.
4) When measuring “CO” percentage, insert probe more than 40 cm (15.7 in) into tail pipe.
5) Turn off headlamps, heater blower, rear defogger.
6) Keep front wheels pointed straight ahead.
7) Make the check after the cooling fan has stopped.
