Highy recommend cleaning the TB it was absolutly filthy and had a serious build up

 

How hard is it to install new belts? I've never done it and I'm at 33k miles. I suppose I should do it?

 

They are prob fine. Owners manual calls for an inspection at 60k so you have a long way to go unless you can see cracks on the inside of the belt. The actual install is very easy.

 

Thanks for posting the p/n for the throttle body gasket. Just out of curiosity, how much did you pay for yours? I see it at rockauto.com for $1.63, but my local dealership is asking $7.05.

 

(Infiniti was asking $7.05.) I also called Nissan, and they have it for $5.40.

 

Thanks, glad to give back to the site. As far as price I worked for Nissan for years so I got everything at cost plus 10%. I prob paid a couple dollars. Good luck clearing the TB code lol I got procudure somewhere if you cant find it.

 

I've seen BythaBay's DIY which is extremely helpful. If you have additional info, the more the better. Thanks again, man.
