Greetings all. I have a 2007 TB LS 6cyl, 4wd, 93K. So far I have replaced both front wheel bearings, added a tranny cooler and electric brake controller, (I tow a 1600lb Aliner camper), new ignition switch and am getting ready to replace plugs and coils, and already cleaned throttle body due to low rpm code. Previous owner took good care of her, did all scheduled maintenance (had all receipts) until I bought her with 68K a year ago. Serp belt is good, no cracks, all hoses in good shape. As I am on a fixed income, I was hoping my fellow TB owners could give me some insight on what I should focus on. Thanks all for any help.
