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.
