ok when my friends and i put my b16a in my 89 crx hf we only hooked up map sensor vacuum line .the car ran good for a few weeks now i start it up and revs to 2500rpm and then goes down when it warms up . what i see on the motor are 2 vacuum lines that are not hooked up will that make my can run like shit cause now when i get around 5000 rpm or more and get on the gas it goes and stops like its not getting enough gas or a sensor . i got a used tps(throttle poition sensor ) cause before the rpm would go up and down that stoped . so what im asking is will those 2 vauum lines make my car run like shit??? thankyou for reading this .

 

which map sensor are you using hopfully not the HF one...
