Problems with bogging down and hesitation.
 

I have a 1997 blazer and it has a tendency to bog down when i take off when i first start to drive or when i start to drive from a stop light or sign. Other than that it runs fine and when it doesnt bog down i have great start offs and acceleration. Have any ideas?

is your check engine light on and if it is check it out could be a mass airflow sensor

Nah my check engine light is off.

I have the exact same problem it sounds like, if you get it figured out please let me know... I'll do the same

OK it looks like i found the source of the problem (atleast on mine) My engine light was on so i took it to advance and it said my map sensor is bad and my vehicle speed sensor, so im gonna replace those one at a time and see what happens.

sav25age, when was the last time the fuel filter was replaced?

about 1 month ago when i put in another fuel pump and gas tank from the junk yard.

It also has a tendency to make a popping noise from the hood of the car when i give it a lot of gas, like if i pull out in front of a car. i was wondering if anybody would know what that was also. thanks

that sounds like it's back firing through the intake. have you checked the timing?

nah i dont know how to do that.
