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.
