Clean my TB... I started getting the hesitation that everyone talks about. So it only took about 35 mins to do both of them. Holy Cow they were filthy!!! Dont worry I have pics. All I can say is that the car runs so smooth now and the idle is dead on at 650rpm. No idle relearn or anything needed. OKay here are the pics....


Dirty!!!


Clean

 

Nice!!! Mine had a terrible relearn for a day!

 

How many miles did you have on your car for the "dirty" pic?

 

I just got the car, but it has 65k on it.

 

no need to relearn... I had to do it, and I didnt disconnect anything..

lucky you!

GJ tackling it yourself

 

Dam thats hella dirty
I have 80k on mine and it looks like your clean pic..lol

 

I haven't check mine! I am gonna take a look at it!!

 

Did you have the high Idle problem?

 

Yeah it makes me wonder... I got the car from an Infiniti Dealer and all the maintance was done there for the life of the car, but dang this thing was filthy!

 

Guys, I've got to say that although that may appear dirty, and perhaps is considered dirty for our VQ's, it is NOWHERE near what's considered dirty on many other cars. That's just a little tinge of varnish; when it can get as bad as a full layer of tar.

 

what did you use to clean it?

 

TB cleaner from Autozone. Cost me about $3. Used a toothbrush and rags for scrubbing with.

 

Very true, i had similar experience in all my older cars but they were all cable controlled and thus the effects of the TB being that dirty was not that noticable until much later, however on all most all these electronic TB cars, even that much dirt is enough to cause uneven idle and butterfly valve movement...

 

i need to get to this at some point..;-/

 

Its well worth 30 mins of time to do it. I bought the new TB Gaskets from Infiniti for $18. Im going to tackle my Tune up and Serpentine belt in 2 weeks. Then its time for the Dyno to get some base lines.
