I bought my 2 door 97 Tahoe in February or March of this year. Since then, I have installed a complete tune up, cap, rotor, wires, plugs, coil, and pcv valve. I have added newer 18 inch wheels and BFG KO2 tires. I have also replaced all AC components and have cold AC. I cleaned the blower motor area. It was dirty but not as bad as I expected. I have also replaced the upper and lower intake gaskets and upgraded to MPFI. She runs so much better than when I bought her. The odometer reads 294,*** miles but the motor internals didn't look dirty at all and the transmission shifts flawless and smooth. She has plenty of power. My next project will be to install a complete new front suspension. So far, I have done all the work but I believe I will let an expert do the front suspension for me. This isn't my first OBS, but it is my first Tahoe and I love it. She is my daily driver and gets a lot of compliments. I have been a member since I bought my Tahoe and have done a ton of research since. I have used the search feature to help me diagnose and make all the repairs that I've done so far. Thank you for all of your help so far. I will let you guys know as I continue to make my Tahoe new again.
