ok so if that not it what else??

 

umm ill tink about it an get back to it an wat else does it do

 

it is just a real bad hesitation when accelerating when cruising u cant notice it just getting going idle a little rough but ok

 

have you taken out the injectors an cleaned them or ran an injector cleaner though them

 

i belive i only have one injector and i am running sea foam in the gas tank and ran it through the intake

 

so i am guessing that you tbi maybe its off time have you haved it timed lately

 

no it is cpi and no timing has not been checked

 

then if the timing is off the truck mite run like wat you are saying

 

You'll be surprised at what cleaning out a clogged EGR will do for your truck. I didn't know that these Vortecs had cam sensors.

 

so i gave in and a friend of mine is looking at it and said they are leaning towards the cat and maybe the map sensor the cat and exhaust looked original what do you guys make of that?
