I’m a poor seminary student near Boston MA (Wenham) looking for a solution for my 2002 Tahoe. I love this truck very much because it fits me perfectly since I’m 6’7 and build like a linebacker. I’m having trouble with the power coming out of the car. Some days it drives very smooth and I have all the power in the world however sometimes it begins to feel very sluggish as if its really struggling to move. There is a faint whining come from under the hood, almost sounds similar to what a turbo on a car would sound like, but obviously there’s none of that garbage on my truck. Sometimes its very audible and sometimes its not so it might just be a squeaky belt. I’m looking for a viable solution that wouldn’t be too hard for myself to solve, I’m fairly handy. just to help eliminate I’ve already had a 100,000 mile tune up on the truck, its currently at 116K, I had the U-joints replaced a year ago, and a fuel pump three years ago. I recently added an oil-honey additive to solve a clicking that was happening when I first turned on the car in the cold, and I usually add a fuel additive (STP or Gum-out) every 1500-3000 miles. And if it makes any difference I’m about due for an oil change. Thanks all!
Peace and Blessings,
