What did you do to your OBS GMT400 Tahoe/Yukon Today?

usually means your converter is no longer doing its job chemically.

Shouldn't cause any driveability issues. I actually have a P0430 I need to take care of. Had it about month.

Ive been rockin the CEL for a po430 AND po440 for almost a year now... hence my interest of replacing my y pipe a few posts ago

 

[yup]

well I'm brand new to the yukon/tahoe world. I just bought a 99tahoe 6days ago and have put in a third row bench seat from a 97 burban and replaced the white hood with a pewter one i found at an wrecker (the color of the hoe is pewter) Now i just have to replace an o2 sensor and it should be all set.

My Guzzletron did a good job of hauling the camper today. I'm definitely going to upgrade the tranny cooler; it peaked at 195 per Torque Pro and the outside temp was 45 at the time. I'm going to order a B&M today and install it next week.

I could definitely tell it was behind me. I was able to maintain 60-65 at 2k when level. It will be a bit easier at sea level, but I'm definitely not going to push it too much.

Replaced the failing alternator today! Pretty easy job. Stress and cussing free for sure.

195° wont do any harm you have to have it higher like 230° for maybe around thirty minutes straight to start to mess up fluid and stuff. Mine goes to 217° on steep roads sometimes with the two factory coolers built on and no towing.
