Hello, I am new to this forum due to maybe purchasing a 2003 Tahoe. It has 74,000 on it and a clean car fax. I am a Ford guy, and have never owned a GM. It is a base model that im looking at with a 5.3l. No leather, no sun roof. I have found out that these have a "electronic throttle body". Are these a problem? I know Ford's are, and the only thing that I have ever owned are cars that have a throttle cable. Any problem areas with these that I should be aware of? Any help would be great. Im just sick of Ford's over head cam engines and want to go back to a engine that is push rod.
