1989 Chevrolet R1500 Suburban Scottsdale 5.7L MIL Lamp on
Hello GM/Chevy experts, I have an 89 Suburban with an intermittent MIL coming on. I have not been able to track down this problem in the last couple of years that I've owned it. The problem comes and goes usually when cold. Please help. Thanks,
