Car Forum / Nissan / Nissan Cars / December 2006"Throttle Service"
Can someone please tell explain what a "Throttle Service" is? What does it entail and what will happen if I don't have one done? My dealer recommended one for $90 on a '05 Altima with 37K miles. I'm not having problems with the car, they just recommended it when I brought it in for my oil change. I don't recall having throttle services done on my prior vehicles (and I've had two other Nissans). > Can someone please tell explain what a "Throttle Service" is?

Is it something that an average person could do, such as adding a cleaner or squirting a cleaner on something? Also, is it something that only a Nissan dealer can do? I can get better prices at a non-Nissan dealer in the area on everything else that isn't Nissan-specific. > arugulasreve...@gmail.com wrote: > > Can someone please tell explain what a "Throttle Service" is?

It is not necessary to clean the throttle. This is hype BS. Forget about it. How many times have you had a throttle stick? If you're like most of us the answer is "never". In the highly unlikely event that it should happen take it to your dealer. BTW, is it a recommended maintenance service in your owener's manual? No, then don't do it.

Funny, I've fixed dozens of dirty, sticking throttles. It's not a big problem, but it can keep it from returning all the way to idle. 10 minutes with a can of throttle body cleaner and an old tooth brush is all it takes. Okay, thanks everyone. I'll pass and save my $90. > Can someone please tell explain what a "Throttle Service" is? What > does it entail and what will happen if I don't have one done?

What I've always noticed when it needs done is the gas pedal (assuming it's not drive by wire) will be a little bit stiff when you first push to accelerate. Sometimes you will also notice the car not returning to the regular idle RPM's. I had a Jeep Grand Cherokee once that would stick terribly if I didn't have it cleaned at least every 30K. Willy If I ever had a sticking throttle body I'd have to wonder if the air cleaner element is properly installed and sealed. If I had to clean it every 30K miles or so I'd be looking for leaks in the intake system upstream of the throttle body. An exception to my position is with aftermarket air cleaner systems that are owener cleanable/servicable. Typically these cleaners have a foam precleaner requireing "oiling" after washing the filter element. Most owners tend to "over oil" these systems thus causing oil to enter the intake system which can foul O2 sensors and possible necessitate throttle body cleaning. Of course, YMMV.

The build up is caused by temp differences I believe (I'd have to go upstairs and get an ase book to validate that statement.) SignatureStephen W.

However, I wonder why Nissan does not recommend TB cleaning as part of the periodic services. Butch > It is a good service on some cars in some environments, Although Fords put > "do not clean" decals on the tb; they are the ones that benefit the most [quoted text clipped - 37 lines] >>> >>> Willy Realistically, I don't recall that anyone of them do. It was a add-on service at my last shop (this one too but not pushed as hard) On two occasions I recall fixing the car with a throttle service (both Fords) One was old enough to have a idle setting and as I removed the gunk the idle went high- I had to readjust the idle to factory specs. Along with the throttle clean is the combustion chamber cleaning- and some cars need this also. carbon can build up on/around the calves and combustion chamber and cause some problems. If a car is having a pinging problem this is one thing to look at/try. To see if toy need a tb cleaning; open the tb and with a strong flash light look for build up around and past the plate. if its clean to slightly dark, and the throttle don't stick- no issue Got gunk? A tooth brush and cleaner and scrub it. SignatureStephen W.
