Asked by Nov 18, 2013 at 11:29 PM about the 1997 Ford Explorer 4 Dr XLT 4WD SUV

Question type: Maintenance & Repair

I have a 1997 Ford Explorer, that has suddenly started to idle very roughly, and the check
engine light, has started to flash. It's be steadily lit for the last 6 year, and never blinked
before. Today it has started to flash constantly. Also, when outside there is a smell
almost like burning rubber, but you can't smell it from inside the truck. Any suggestions
what this might be?

Thank you for your help! By cat do you mean a catalytic converter? and also what is an egr valve?

5,700

yes thats what i mean by cat. The egr valve controles the emisions. it is normally mounted by the carb and can be ran by vacume or electronic. 1997 I would say is vacume check for a vacume leak going to it. looks like a silver diaframe with a vacume hose hooked to it and 2 bolts holdint it in place

The check engine light is flashing to warn you that the engine is misfiring and damaging the catalytic converter!! Have the computer scanned for trouble codes. Since the check engine light has been on for 6 years (I'm hoping that's a misprint!!) you'll have more than one code. If you have over 100,000 miles on your Explorer it's time for a tune up. The EGR (Exhaust Gas Recirculation) valve is an emission control device that routes a small amount of exhaust gases back to the engine to be reburned. It reduces hydrocarbons. HTH. -Jim

Thank you so much for the help. The man who came to look at it said it was partly my serpentine belt (which was very very shiny) and when I said the thing about the spark plug he checked it and said that it was part of the problem too. He has already fixed my truck for me. Thank you all again for your help!
