recently swapped the motor on my 5speed civic 2003 1.7l just a d17A1 and when she fires up it revs to about 3 then down over and over i got all my sensors plugged in sounds like there is vacuum issues or maybe I'm missing a wire or possibly something else i was wondering if anyone had a good diagram for the vacuum lines and for the wiring harness

 

my 03 Honda Civic is doing the same thing put a brand new cam sensor in it next it crankshaft sensor I can’t figure it out been like that since I got the car so I just ran it till i crashed it and turnt it into a race car
