I'm curious to the above answers especially to Dodge man, How can you take a pre-OBDII vehicle to Auto-Zone to get the codes pulled. FYI ODBII is from 1996 and newer. This guy has a 1991. A 1991 wont set a code for catalyst efficiency because it doesn't use an O2 sensor after the cat
To your question you can try with the basic maintenance (plugs-motorcraft, wires, cap and rotor and O2 sensor). You can take a can of carb cleaner and spray around component and listen to the engine for a raise in rpms to check for vacuum leaks. If you feel like doing the above and spending some money this is a good place to start. I'm sure the truck may need the above anyway. If you do these repairs disconnect the battery to clear the check engine light then drive. If the light returns you will need to have a diagnostics done.

Check engine light are usually emission control problems. More likely it is one of the many sensors. It does not mean that the sensor is bad. It will give you an idea what that sensor is monitoring which will direct you to the right problem. have it checked with a scan tool. It will save you a lot of time and will tell you what exactly is wrong. A well trained mechanic would do the same thing than spending time checking each and every sensor... Good luck

As others have stated, get the trouble codes pulled from the electronic control unit and fix the problem right away. Things like a bad Oxygen sensor can hurt the life of your catalytic converter by quite a bit, costing you more $$$, it will also hurt your gas mileage. There are other sensors that if left unattended, will hurt the life of your engine and the environment.

Could be an oxygen sensor in your catalytic converter? Usually in Fords when a check engine light comes on it is emissions related.

You can go to an auto parts store such as Auto Zone or Advanced Auto and they will check it for you Free of Charge. You may have a serious probblem that needs to be fixed.

i own a repair shop,and if you,ll take it by any auto zone they can scan it and tell you which sensor is bad on it that's causing this to happen ,and its free,that way you,ll know ,don't ever start buying parts for one of these without knowing exactly whats wrong with it ,that can get really expensive after a while,good luck,i hope this helps.
