Fuel/air mixture problem ka24de

[futureS13]

i just got a 89 240sx with a 96 ka24de. when i go to it in the morning it takes probable 8-10 tries to actual get it running and even then i cant push the gas at all or it will bog out. once i get it going that first time by babying it it runs fine. not really sure what it could be im kinda new to the working on cars thing. i changed the spark plugs fuel pump spark plug wires and valve seal cover. i noticed that there were two unconnected sensors just chilling in the back behind the head. does anyonoe know what that is? or if it causes bad start ups??

now in almost every gear when i give it more then a little toe of gas it trys stalling. is that a possible o2 sensor?

two connectors are probably for the egr system. take a pic of it so we can see what it is. try checking the timing on the vehicle
