I have a 99 Trailblazer and it will bog down when I take off. It does not do it all the time. It seems to be after I put gas in it or right at stat- up. When it is driving it does not seem to be missing or anything. Any sugestions ?

 

How many miles on the fuel filter? Have you checked your fuel line pressure?

 

had almost the same problem on my 97. replaced the fuel filter and the problem went away. try that and let us know
