Alot of people forget to clean the throddle body and it does help alot, For only 5 bucks you could buy it and take out our intake connection and just spray with the engine off and open up the valve and spray the inside and you would be surprised to see what the hell comes out of there and if you want to check just open up the valve and rub your finger on the inside and i bet a nice heap of black gunk will come out but anyway use the whole can and let it dry for about 30 mins or 20 mins is fine cause it's alcohol based and then connect everything back and start your engine and keep your foot on the peddle at about 2000 RPMs and it will try to shut off but that's normal and keep it there for about a min and then take it off even less than a min in fine.

Then shut off the engine and then turn it back on and everything should be fine and your finished.

I takes about 20 mins to do and you will save gas and get a better pull on the highway and this mod is about 5 bucks and really make a difference so check it out!

 

THROTTLE

12600 users and nobody thought of this....

 

You have just entered the Guinness Book of World Records for the following achievement:

WORLD'S LONGEST SENTENCE

You also might want to try using a rag to wipe out the gunk rather than just spraying the treatment in there and "letting it dry".

If only I had a :shakehead: smiley...

 

This procedure is incorrect! Please don't do this or you will wind up with sludge sitting on the bottom of your throttle body and part of the intake manifold.

Please follow the cleaning instructions on www.motorvate.ca

Thank you!

nice write up!

is there any thing else i can get at Pep Boys as far as the spray cleaner u got from canadian tire?

 

Get the intake cleaner from Pep Boys, get a tooth brush from Shop Rite and get some nice LINT FREE paper towels to wipe the inside of the intake clean. Stuff the paper towels as deep as you can get into the intake when wiping out the crud. I wrap the tooth brush with the towels and use that to wipe away the crud after I brush it lose.

EDIT: Don't forget to wipe down the throttle plate as well. The back side gets really dirty.

 

...FWIW, cheap dollar-store coffee filters are great lint-free wipers for jobs like this as well as for cleaning glass...

 

Actually, throttle body cleaning using the spray is a great idea in most cars - but not the Maxima. Nissan has coated the throttle body valve with a special polymer that is supposed to keep the gunk off. If you spray the cleaner in there you will damage the coating and gunk will really build up. They recommend you use only a soft cloth for wiping it down. You can, I believe, spray through the PCV valve while the engine is running and that WILL clean up the crap in the intake manifold that comes from recirculating the crakcase fumes. There should be nothing to harm via this route.

 

I thought practically all throttle bodies were coated with a special material, hence the need for a specific throttle system spray and not just a normal carbon cleaner product. Dunno though, that's just gathered from some .org research in the past. If there is a special polymer in the nissan tb, and its purpose is to keep the gunk off, it doesn't do the best of jobs anyway.

 

You won't damage it if you use a product that's safe for the coating. I believe 3M makes it.

 

Thank you. Yeah a full can is a bit excessive for starters.

 

just did mine
alot better

 

 

What are we in English class? You know what he means. Don't bash a guy for trying to help others.

 

will be doing mine tomorrow, and i did get a special cleaner for the throttle body thanks to this post because i was ready to use some carb cleaner. Thank you .org

 

anyone know if Valvoline SynPower Carb, Choke, and Throttle Body cleaner safe to use on our cars, without damaging Nissan's special, polymer coating? i know i've used it and a lot of other .org members as well

i've directed them to my post via feedback form on the website, so maybe we'll get a response

 

I had a question.. sure, spray stuff into the throttle body... what happenns if you get some back there so deep you cant get it out? is it ok for the engine?

 

A LOT.

 

i just cleaned out my throttle body again today, as well as my IACV and whatever i could reach of the intake manifold through the IACV opening (i got a LOT of gunk out of there!! and hosed down the upper tube with cleaner as well) - and it looks like Valvoline SynPower doesn't destroy the special coating near the butterfly valve, as far as i can tell

what was/is wrong is that my IACV was/is clogged, i'll find out tomorrow morning with a cold start if i finally got it clean enough - if i didn't, the engine will choke and struggle to start like it's been doing the past couple of weeks

one thing though, is that i could feel my car jerk whenever i let off the throttle (and went back on idle air) but that's gone now - funny, i thought it was a motor mount causing that jerk, but now i understand why my engine isn't moving too much when i test for motor mount failure

so now i'm thinking it might be the driver's side control arm bushing or a sway bar bushing that needs replacing, and is causing a persistant crunching noise whenever the car starts rolling or comes to a stop

 

I was busy everyone had i made a typo damn, Everyone's busting my ***** for reminding people to do this and it does help alot but anyway thanks to the few that aren't 12 Max

Well, just picture how the .org would be if ten new people every day came on ranting in light-speed speak like they just found the one holy almighty maintenence operation that restored your car to off-the-showroom-floor quality, and all for $5 and 30 minutes.

Now think of how it would be if all ten ended up posting an incorrect procedure for a quick & easy maintenence operation that most members are quite familiar with.

I know about the good intentions, but even with good intentions, it'd get old if we had 10 new posts a day telling you to change your engine oil, and explaining the procedure with the wrong weight of oil.
Not to mention any possible negative consequences from using a slightly incorrect procedure.

 

It's not an incorrect procedure, You have to spray inside, The gunk get's removed when you push it at 2,000 RPM like i said.

It doesn't just sit there and build up, It's goes into the combustion chamber and gets burned up and leaves.

I went to that website, That the guy on the first page posted and all they said was to spray the valve and that's bull**** because even on the can it says to spray inside and it wouldn't do anything if you just sprayed the valve.

You don't do this to your car and just start the engine and leave it alone, IT's gonna shut off.

You have to burn it up and it comes out as white smoke from the muffler and it's gone after about 3 mins.
