You can try to unhook the battery, but that usually opens another can of beans with having to reprogram the radio and all.. OR, you can take it by AutoZone, and have them read the codes for you, and then reset the light. If the light comes back on then you have a problem. Correct the problem and reset/clear the codes with a scantool.

Question:
I keep having my 1997 GMC Savana 6.5liter turbo van shut down to idle with “Service Throttle Soon” light on the dashboard. What is the problem and about how much will it cost for repair?
Answer:
Its either the accelerator assembly. the throttle actuator, or one of the circuits between these components and the computer. I do not think you need a computer at this point.
You have to allow an hour of diagnostic time plus parts and replacement labor. I can’t see this cheaper than $300.00

P0171 : System too lean bank 1
P0174: System too lean bank 2
These codes let you know the O2 sensors are creating a lean condition. Since it is apparent on both sides of the engine we can rule out a blown head gasket or injector issue. We can even rule out a misfire. The majority of the time this is caused by a vacuum leak. There are several hoses that can become weak and collapse. Pay close attention to all the vacuum hoses. These codes may be accompanied by a rough idle. Replace the hoses as needed. On some vehicles you may even find the intake gasket leaking(plastic intakes).

How can I tell if My Car’s alternator is charging ?
There are a couple of ways you can do this. One is by using a multi-meter set to DC Volts. If the meter shows less than 13 Volts it is not charging(this is done with the engine running). Another indication is if the icon on the dash that looks like a battery illuminates then the alternator is not charging. Typically the alternator will produce 13.5 to 14.7 volts. If it does not you will need to replace the alternator. Make sure to check this after installation.
