<![CDATA[2problems. need help]]>I have 2 problems with my 300z. One is, when it sits there and idles, it idles at 1(rpm) but after 2minutes, it drops down to damn near 0. Now my question is, is it a terrible misfire? Never had this happen to me on a vehice.

  1. anyone in here do exhaust work for a decent price?

This screw, with all accessories off. Should be 800 RPM. :icon_geek:

Right when I get off the gas, it sits at 1grand then goes down close to zero. Warmed up or not. I dont wanna fuck around with the idle by myself cuz I dont know what I'm doing so I'm mostly likely gonna pay outta my azz to have someone look at it.

Is the air condition on or off?
Heater fan on or off?
Headlights on off?

If any of these are on the computer bumps the base idle up a few hundred rpm.

As soon as I tap the gas, it stays at 1grand then goes back down after 2minutes. Has no hesitation, runs good, just having the problem with the idle.

If not you need a new IACV. Is it 2 min or after your temp starts to turn up?

If is pretty much consistantyl 2 min no matter conditions, then its something related to open vs. closed loop and you should probably be throwing a code.

2: Do it your self or spend $$$$
