Have someone check it with a different scan tool it possible.Not all scan tools will work.If the light is coming on and you notice the vehicle is not running the same as before,there is a code in there and you have to get that code to diagnose the problem.

Car seemed hesitant when started service engine soon light on

There are many things that can cause the light to come on. Generally if it is serious most 'check engine' or 'service engine' lights will blink. The simplest (and cheapest) method to diagnose the problem is to take the car to AutoZone and they will read the computer codes free of charge and tell you exactly what it is (such as the oxygen sensor got a bad reading and needs a reset, or its time for an oil change... etc.)

My service engine light comes on,and the exhaust coming from the system smells like it si not burning right. The van periodically shuts down. What would I have to do to solve this problem ?

First you need to have the computer scanned for trouble codes. Then we can help diagnose the problem further. If you have a Autozone nearby they will scan the system for free, so will many other auto parts stores. Please post back with the trouble codes when you can.

Service engine light on

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. You or a technician will have to perform further testing to pinpoint cause and the proper repair. Even if you reset the light, if the underlying problem is not addressed it will come back on.

98 C1500 Silverado ''service engine soon'' light

the service engine soon lite comes on due to an input sensor to your vehicles computer that has gone out of its parameters. this lite does not come on due to mileage. the computer needs to be scanned for code #'s in order to diagnose correctly. autozone will scan codes for free. if you get me the code #, ill try to assist further, otherwise you may want to see your local garage.
