My 1997 Altima with 120k passes emissions, but fails overall smog inspection because "MIL/Check Engine Light" results in "Fail".
The bulb is fine, as it illuminates, then promptly discharges upon starting.
Two smog guys have said all that's needed is to run the car @ freeway speed for about 30 miles, which I've done five times over, to no avail.
What else can be done to rectify "MIL/Check Engine Light" failure.
