I have a 1995 gmc truck and when you go foward or backward the anti lock brake light comes on and after you drive it about 5 miles the service engine light comes on and it will not go off until you cut the motor off . I had it put on a machine and they said they couldn't find anything wrong .what is my problem with the anti brake light and the service engine light.

check your grounds to make sure they are good and then check your battery, if it's in poor shape it will screw up teh computer system.
