Excuse the language but I think my Eg has a vacuum leak somewhere. Thing is it did it when I first got the car 3 years ago, swapped out the old d-series non vtec with a jdm d15b. It went away for a little and did the same thing again, and now its been doing it constantly and way worse.
When I'm stopped and idle the motor surges or revs up and down like its breathing in and out heavy is the best way to describe it. I did some research and I found something that lead me to believe it might be my throttle body. I think when I put the new motor in I used my old throttle body off the old motor, so if that was the problem it wouldn't of went away.
My real question is how do I locate a vacuum leak if that's the problem? Or if its not the tb then what else could it be?
