hey peeps. i have a question for someone. i have a 2000 blazer and it just started this hesitation thing when goin highway speeds and sometime when you go to take off from a stop. the check engine light has never been on in the 2yrs ive owned it and ive done a minor tuneup. i havent changed the fuel filter, the air filter, or the o2 sensors. i love my vehicle and dont want to be stranded. so could you help me make my blazer blaze again or give me some tips on what could be the problem.well gotta go back to work, just let me know something as soon as someone gets a chance. thanks, budda

 

Has the fuel filter been changed in the time you've owned it? Sounds like that would be he easiest and cheapest thing to try first ($12 or so for the filter) and I think you need like a 3/4(probably 19mm actually) and a 22mm wrench to change it.
