dash light
 

Just got a 2000 Mustang conv. 6 cyl. 47000 miles. after driving about 20 miles lite on dash..."service engine soon" came on. What is required to turn off that light? I usually do my own oil & filter changes.
B:confused:

could be several things. get a repair manual to find out how to read the codes from the computer. if you know it is a false light, i t should tell you how to reset the computer also.

disconnecting the battery for about ten minutes will get rid of the check engine light if the problem is gone
