2003 Ford Ranger 4 cyl 133,000 miles. Cat is glowing red after a 15 minute drive and then idling for a couple of minutes. Stayed red hot at idle. Even the pipe behind the Cat was glowing for a few inches.
The truck runs very rough at idle but at speed it runs fine.
Does this mean the Cat. is clogged up and needs to be replaced?
Is this what is probably causing the rough idle?
Thanks a ton!
