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

Use a can of starter fluid to check for leaking gaskets, ensure your injectors are seated and plugs are tight with no frayed wires. White running you can pull injector wires one at a time too, if the mirror doesn't change when you unplug an injector either you aren't getting fuel to that cylinder or your aren't getting spark there.

I got it running but still not fixed. Pulled throttle body off again and put new gasket. Realized the hose that goes under throttlebody to throttlebody wasn't connected so connected it and adjusted throttle a tad bit and was running. Pulled it to road and stumbles bad from stop to 1esrt gear. Had to floor it gurl it stumbled and stumbled and stumbled and finally got a little power. And then drive and limp back home. Glad I was a street away otherwise id have to ditch it and walk home for my dolly

The iac is a common failure on the ranger I replaced one twice on my 98, pick up one from the junkyard cheap and see if it helps

Had the rear axle gear oil changed to Mobil 1 synthetic. you can find some photos of it here. http://s1222.photobucket.com/user/Sunlitcomet/library/1996 Chevy Tahoe 4X4/Rear axle?sort=3&page=1

Existing fluid life unknown as it was in there when i got it in 2010. It is believe to be low on fluid level as well over the past year at least with leaking gasket.

Mine would ask me to do oil pan gasket and blend door actuator
