2000 Blazer - 107,800 mi; standard V-6.
'Service Engine Soon' light lit, but no trouble codes appear on code reader (code reader is functioning on other vehicles).
The MIL has come on before, once two days after dealer performed 90,000 mi service; said it was minor glitch; not to worry. Shortly after, the MIL came on again, but went out before we could get it back to the dealer. That was about a year ago; now, the MIL is lit again, but with NO CODES.
What is your take on this.
