I removed the throttle body yesterday to clean it, and as I suspected, the idle was thrown off. Should I adj. the idle so it as 1k or 500 at idle? There are two cables, so do I adj. the one that open and closes the throttle, or adj. the cable next to it?

 

Mine idles at 1k. one of the cables goes to the pedal and one goes to the cruise control. you need to figure out which one is for the pedal and adjust that one.

 

those cables will only adjust the tension. the top cable is the accelerator if im not mistaken. just pop the hood and tap the gas and watch which one moves. the only way to adjust idle is hook it up to a consult 2 machine which can be found at your local nissan dealer or if you are lucky a local nissan specific shop.

 

idle on the max is adjusted by an ECU change.

 

which is done by a consult 2.

 

I figured it out. I tightened the throttle cable so it left the throttle opened slightly. thanks for the help.

 

So it must be done by the dealer for auto and stick? hhmm .. Do you have to make an appointment for that??

BTW .. mine is idling between .52-.60 K .. which is very low i think ...

 

Thats not the way to adjust your idle speed! Put some slack back in that cable or your going to have driveability issues. That cable will expand when it's hot idle goes low, and contract when it's cold which is going to give you a very high idle which may render the car undriveable. What you've done is borderline dangerous.

 

your dealer might actually do this but dont count on them advancing the timing. the procedure is the same for auto and stick but the settings are different.

 

 

OMFG! Thats a hack way of adjusting your idle! and your gonna bugger something up that way. Chances are if your not idling around 650 rpm there is something wrong... MAF, vacuum leak etc... My suggestion is to put your cable back the way it was ASAFP!

 

My bad. I stated that wrong. What I meant was, when I put the throttle body back, my adjustments were too tight and the throttle was opened slightly, and that is why the idle was at 1200k. I readjusted it and it is operating normal now. In no way was I trying to adjust the idle. There isn't that much lag time between stepping on the throttle and engine response as there was before. Is there anything else I can do to get rid of the lag?

 

how many miles do you have on it? im thinking new spark plugs and perhaps a bottle of chevron techron fuel system cleaner will probably get you close to the way it was new.

 

61k and I replaced plugs last summer. Maybe I'll try that system cleaner.

 

Maybe a throttle body cleaning to go with the fuel system cleaner? Air cleaner restrictions?

ARFF

 

he already cleaned the throttle body, read his first message. if the air filter is dirty then i would replace that before anything, but im assuming if you had the plugs done at 60k then im assuming you keep a good eye on the rest of the maintenance.

 

Derrrr..... Dummy. I knew that. (talking to myself)

YEah, new air filter? Plugs were gapped properly? Nothing's loose or torn on the air intake? Try the fuel cleaner like someone mentioned.

Usually I read better...

ARFF

 

air filter on the intake was cleaned on the same day. I'll just try that system cleaner and see what happens. Thanks for the input guys.
