i did a swap on my 92 hb with a b18a1 it starts up ever time it just wont idle and when i hit the gas it will kind of die and then it revs up what could it be? i replace the injectors with the ones of my civic because i was told they were better becasue of the resistors could this be the reason or could it be a mass air sensor?
 
check the mass sensor and the throtle body sensor, If the throtle body sensor is mess up thats why it dont idle and the mass sensor is the one that usually makes the car rev up and down.
 
Double, then triple check all of your vacuum hoses. Make sure they are routed correctly and not leaking or cracked. Check for open ports.
 
ok ill try that thanks alot oh and i have no exaust right no its stright piped all the way back but that just build back pressure right so it sould still idle?
