Bought a tahoe with some minor issues

First off- welcome to TYF!

Secondly- You posted this in the 1991-1999 forum. Posting in the correct forum may get you more help. Since he loves moving threads, let's see if @NathanJax will help

And, now for your problems- Either your EVAP system is clogged up (bug mess) or it could be as simple as the vent hose is clogged. I just performed this repair on mine a week ago. ALL of the EVAP system hoses were clogged from the carbon/charcoal pellets in the EVAP canister being leaked into the system. I replaced the canister and vent valve and used compressed air to clear all the hoses from the purge valve solenoid on the intake manifold to the fuel tank, and all the hoses on the tank itself.

Sorry my bad.
Thanks for your help. Its difficult to find good help here. As most garages are run by people who just know how to change engine oil and fill AC gas.

You need a real scan tool to read codes from the airbag. A hand held code scanner usually can only read codes from the ECM.

Yes I tired 2 scan tools
Launch
Autel
The ones with big screens. But didn't show up on both.
