the other day i was sitting at a light in neutraland i noticed my rpms where at 1500 it was like the throttle was stuck and it was reving. later it when down on its own but started doing it again shortly after. is my throttle cord sticking? because when i rev the ingine and let off gas quick it returns to normal. can anyone please help me out?

 

Sounds like your IACV or throttle butterfly-plate is sticking.

Clean out the throttle body thoroughly and the IACV too. You might need to pull the TBn off the car to clean it thoroughly.

Check the stickies for information on how to do this maintenance.

 

checked out the stickies seems easy enough anyone have any advice who has done it? what is the TBn?

 

TB => throttle body

 

thank you. is anything going to come out od the hoses when i take them off?

 

A little coolant might spill from the TB coolant lines, but you might be able to clean out the TB without pulling off all the lines - just need to get it off the plenum so you can get the back side of the plate.

Nothing but air lines to the IACV - so nothing will spill.

 

thanks im going to do it this weekend

 

If you do decide to remove the throttle body, make sure you have a new gasket. I just bought one yesterday for $4.51 USD from the nissan dealer in my area. The gasket is paper, and you won't want to reuse it. Or you can do what I did and tied a slip knot in a piece of string and slip it over the little nub on the throttle linkage. Then find a secure place to tie the other end to , to hold the butterfly open while you clean. Just be sure you untie the string before you try and start your car, I wouldn't want to hear any horror stories of how someone blew there motor by cleaning the TB.

 

hey does autozone carry the gasket or only nissan? im trying to avoid giving the nissan dealership near me anymore money they have ripped me off in the pastand i no its only 4 bucks but still. what is called just a throttle body gasket?

 

Probably a dealer only item - but call and ask at Napa, Autozone, etc.. you might get lucky... and yes, its called a throttle body gasket. I recommend replacing the IACV gasket too (if you pull that off)... its a metal gasket... likely dealer only as well.

 

any idea on iacv gasket price?

 

5 bucks or so IIRC

 

You havnt done a TB Coolant line bypass have you?

 

no TB coolant line bypass i dont think lol
