What makes my 99 Tahoe stutter while running idle and bogs out when applying acceleration?

I have changed and up-graded fuel pump, change map sensor, changed in-line fuel filter, and replace cap & rotor. Is there any hope for me?

What about the plugs and wires? They are even more critical.

The injectors could be an issue as well. A cleaning by a shop can clean them up.

Did you have a check engine light?
