Ok, I assume it is a V6.

Control module? New and did you get it flashed?

Injectors could be fouled. Have them cleaned professionally.

Additive rarely work and is not effective.

Did you do a compression test?

Ok, sorry, I thought you meant the pcm. Thought it was a v6.

Flashing is the programming in the computer. Just like your home computer, there are updates to yours as well.
