When I press the gas pedal from a stop I hear a noise in the engine, almost sounds like a vacuum or something. It did it when I bought the car off the showroom floor. Since mile 1. I have 14,000 on it now. Still does it, anyone heard of this before? anything similar or any suggestions?
And one more question. Does that throttle body adjustment really work, or do anything good?
Let me know,
I was told that the sound is air rushing into the intake. I dont know if this is true but its wat I was told by a few people. As for the Throttle cable thing I would not do it. I was told by many Mitsu people that it is not good to mess with it and some members who regreted doing it and I feel the same way. I took my car back to the dealer so they could re set it.

THROTTLE CABLE MOD
the only reason a member would regret it, is if he/she pulled it TOO far. this would create a tremendous pull on the engine when it is just idling. this would also bring your MPG in city, maybe even highway, way down because of the same reason. It would feel like you had your foot on the gas and brake at the same time if you were at a stoplight. The way you are supposed to do it is to pull it just enough to take the slack out without raising the RPM's.(you may need someone in the car to watch the gauge, or if you have a good ear, you can judge it that way) The actual reason for doing this is to quicken the response of the accelerator. It doesnt give you more horsepower. Raising them between 100-300 RPM's is not going to really effect the car at all. Raising it 1000-2000 RPM's, or pulling it all the way tight is really bad and you will feel it. I have not heard one person say they regreted it
Hopefully this gives you some insight to the positive aspects of this mod.
My dealership actually sets it a little past just tight...the TB is open very slightly.
for those who didn't know. the service manual calls the throttle cable the accelerator cable.
as for how tight to tighten the cable. the service manual suggests 1-2mm in slack.
