My 2000 S-1o Blazer (94k miles) 6 cly, auto, 2wd has begun hesitating after driving it. When I accelerate, the is hesitation and sputtering, but quickly ends and vehicle runs appropriately. I cleaned the throttle body (which was quite dirty with carbon). This hash helped, but not alleviated the hesitation. I have never tune up the vehicle. Should I? What should be replaced? Are there any issues that I need to be aware of should I attempt to tackle this on my own?
