Re: Why could my 1996 yukon running rich
First. Get your truck to a parts store that will run the OBD check. That will tell you alot. Next, check the air filter...if not, check the air horn on the throttle body for carbon buildup. Remove the air duct, spray a clean cotton rag with solvent and wipe thr carbon out of the air horn.
