wierd rev question..
Ok I run 18x8 Moda R6 tires. I was noticing that when I pull into parking spots I hear a wierd creak...so in an effort to further investigate the "creak" I sat in a parking spot and moved the steering wheel back and forth. To my surprise, the engined revved each time I moved the wheel back and forth! It didn't rev extremely high, but the rev is noticeable audibly and visually as I could see the needle on the tach rise and fall. Is this normal? If anyone else has come accross this problem let me know.
Thanks

There is a pressure switch on one of the Power steering lines that has a couple of vacuum hoses attached that affect idle. I don't remember what Nissan calls it but I remember reading references to it when I was reading the manuals when my IACV failed. Maybe that that switch has failed. It is located right rear of engine compartment.

Its a high pressure line Power Steering switch telling the ECU that you are turning the wheels and it bumps the Idle Air Control Valve- IACV, duty cycle and thus increases idle speed to prevent engine from possibly stalling. PS pump takes some power to run, and the engine isn't making a whole lotta power at idle eighter.

wow thanks guys, at least I know it's normal. One more question, I got the rims last summer, and they were fine, this spring when I put them on, the faster I go, the more the car shakes, do I need to have the rims re-balanced or could this be another problem. I simply had my winter tires/rims (oem) taken off and my Moda rim/wheel combination put on. Thanks again.

Ihad the same problem with my car. I have a set of Motegi MR7's. After having the tires re-balanced, I still had vibration at certian speeds. I invested in a set of hub rings that help center the mags. That did the trick for me.
