MY 89 S10 BLAZER 4.3 AUTO. WHEN YOU ARE DRIVING DOWN THE ROAD AND PUNCH IT A LITTLE JUST TO ACCELERATE NOT TO BURN TIRES , IT BOGS AND HESITITES A BIT THEN IT WILL GO ON. NO BACKFIRING OR SMOKE. COULD THIS BEE CARBON BUILDUP IN THE EGR VALVE OR AM I LOOKING AT SOMETHING ELSE. THE ENGINE FIRES RIGHT UP AND IDLES GREAT. BUT THERE IS SOMETHING GOING ON, ANY ADVISE WILL BE APPRECIATED. DON

my blazer does the same thing sometimes but i think i have solved the problem dont use 87 octane gas use 92 and it seems to help. but still has that little hesitation. but not as bad as it normally is.

It also wouldn't hurt to put some gas treatment, fuel injector cleaner, carb cleaner, etc. There is a bottle you can get at Wal-Mart for a few bucks. It's by Prestone or something like that. It's in a silver bottle. It's a complete fuel system cleaner. I use it once in a while a it does make a difference. Awesome stuff.
