O.T. SES light on Chevy 1500

Posted by KSwhiteguy on April 29, 2006 at 19:13:00 from (158.247.204.127):

I don"t post too often "cause generally most of my questions will be asked by someone else...

My problem?

Got a 98 Chebby K1500, 93K one owner miles (me), 5.7L (350ci), fairly well maintained.

Smelled coolant for quite a while, finally took it to the dealer. Replaced intake manifold gaskets and other stuff. Seems Duracool or whatever eats "em up... That"s their story. Cost me $850. (Still smell coolant, only not quite as bad.)

900 miles later, the Service Engine Soon light comes on. Took it back. They say bad catalytic converter. Want another $800+. I say "bad sensor?". They say "nope".

The local muffler shop will replace the converter for way less than $800. But, will that fix the problem? BTW, it seems to run good, quick as ever, haven"t checked gas milage for a while but doesn"t seem abnormal. The exhaust system is original and unmolested.

Is there a way to check the sensor? I would hate to mess with the original exhaust only to find out the sensor was bad, but on the other hand, if the converter is bad, why mess with the sensor?

Has anyone else run across this or something similar? Any ideas?

Any help would be appreciated. A trip to Atlanta is planned for Memorial weekend so hopefully everything can be fixed before then.

Thanks,

Claude
