I have a 98 tahoe 5.7 4x4 showing no ses on startup. On hot or humid days if I try to gun it it will hit 3k and just bog down as if it's struggling to go anywhere. I can literally have my foot to the floor and it will sit at 3k and go maybe 40. If I let off and easily coast up to a higher speed it will get up and go but still run funny as if there is a stumble. Fuel gauge does not work but pump was changed last year (very noisy at all times) not sure if that has anything to do with it. The last code the truck had was MAF sensor which I never changed I just reset the code and the light never came on again.
any ideas?
