As soon as I put new ones in and hit the key on they would blow. Found the ground on the back of the head passenger side to be barely hanging on. Cut splice and...

    I want to clean my own throttle body, I feel like it’s pretty easy to do. But I’ve seen some guy on YouTube with a third GEN Tahoe that had to use a computer to reset the RPMs at idle after cleaning it. Is this so? And what’s your guys experience cleaning them? I feel like I’m losing power...

    Delayed shifting after throttle body cleaning

    Hi guys, I have cleaned my throttle body and the MAF sensor couple of weeks ago. After the cleaning my 2013 Yukon is not shifting gears as before. It is like it hesitates the shift itself. I haven't had any codes. Also the car idles normally. Any ideas what it could be? Thanks
