help me with my RX 7 pls
 

hi Guys I have an RX 7 model 1994 and when i press the gas pedal sometimes it works fine but sometimes when i press it down from 1st to 2d gear it goes completely like in save mode. It goes completely flat like goes in 0 and then goes out in a sec when gas pedal is pressed down,

in normal slowly running works fine and starts fine too. it just like floods when gas pedal is pressed.

Can anyone help me out please what i need to do?

the more the car heats up the more the problem
