The engine light came on in my '03 Silverado yesterday. (the second time within a month) I took it in to the shop today and it turned out to be the cataletic (sp?) convertor. Has anyone else come across faulty convertors?

How was this determination made ?
Did the shop do an exhaust-gas analysis ?

convertors?
Well, normally they do a 'puter scan. That would give you the results. There is an oxygen sensor before and after the converter

It could be the rear O2 or the cat....You can tell with a scan tool.
No, I haven't...

Converters are way more reliable than sensors - which seem to have a very high fail-rate.
Lots of fleets ignore the light completely. That goes for fleets with "virtually unlimited" vehicle maint budgets too. The sensor failures occur from right off the showroom floor - and often don't signify much except low quality sensors.
Not in my case, the converters interior fell apart causing a blockage, reduced power and a flashing engine light. Had the converter replaced today and all is well again (for a moment. Me thinks the truck is a lemon)
