In the morning when i first start my car it has no power, when i start to drive every time when i shift from 2nd to 3rd it will spit flames out of the pipes and when it warms up itt runs fine, and once it worms up i cant floor or it will fall on its face, but if i gradually get into the throttle and floor it at 3500 but if i'm under 3500 it just falls on its face. I think its loading up on fuel. What do you guys think i need to fix this? any help will be appreciated.

 

fuel filter? injector clogged?

 

double check your timing.

 

it only happens when its cold, also when its extremely cold like after its been sitting over night it will pop through the manifold

 

might be an intake leak

 

crap, cuz when it warms up it rides out, and i noticed it makes not a lot of vacuum at idle, i'll check all the bolts tomorrow, but i trust Donnie, He works around mustangs all the time, he owns boosted performance.
