I do recommend returning to the smog station which fixed your Ford Explorer
two years ago to find out why the SUV failed this time again. Was it for the
same problem, or has a new problem emerged? Also, after they fixed the idle
problem 2 years ago, how long did it take for it to reappear? If it was soon
after the repair, you want to find out if they changed the Catalytic
Converter just to get the car to pass without fixing the actual faults.
Return to the smog check station and ask these questions. Get back with us
for follow up.
