+2. Best stuff out there. Their CF5 is a good product as well. One is for the initial cleaning and the other is for maintaining, I can't remember which is which right now. I think the CF5 is the cleaner and 44k is the maintainer, but that may be backwards.

Can someone please send me a picture of what vacuum line to use? I got a can of seafoam spray and everyone says to spray it in the throttle body. I used to spray it in the line comming off of the master cylinder.

You can do either the TB or vacuum line.
the vacuum line is easier and more controlled rather than pouring it into your TB.

I'm not to sure about Seafoam. Coming over from the Tj forum-- where it's not recommended by some of the knowledgable guys. Now is the 4.0 or 3.8 and different--I don't know

"they" say it is a-ok and I have no reason to think it would do any harm. The vacuum lines arent rotten or cracked that I can tell. My biggest comcern is the resulting oil change. I am thinking I will pour some in the oil and flush at the same time.

Ummm.....if you want to clean your injectors you need to run a chemical through them. Putting it in through the throttle body or a vacuum line won't do that. If the goal is to clean the crud out of the intake manifold that will work. It won't do anything for your injectors.

so how often do you think one should run a fuel system cleaner through the JK engine? I am thinking more preventative maintenance since i'm running and idling OK now with around 10K miles.

I try to about once every 5-6 weeks, and as a matter of fact last week the 3.7 in wife's commander was idling just a hair rough, so I give it a injector cleaner and a couple days later it seemed to be gone, knock on wood

Well, I run it through my injectors every month, but I haven't cleaned the throttle body or intake manifold since I got it. I just didn't think it would do as well through the t/b.

so just a can of this beloved Seafoam direct into the gas tank with a full tank of gas is all that is needed?

Total guess here ... 30,000 ??

Bought my Tj new and for it's life I always went through the whole jeep in 30,000 increments. Probably overkill but it still ran
great at 160,000 when I got rid of it.

I bought the Jk at 35,000 and dealer said they "went through it" but I would like to start from scratch. Already did the oil, plan on spark plugs next and a bottle of that Techron fuel system cleaner. Finally before winter the rest of the fluids tranny/diffs/TC and then-- I will be happy

What is the best way to clean the TB on a JK?

A good link will Do

Different then the TJ with the electronic throttle control.

Take it off and clean it with throttle body cleaner. Wipe out what you can reach in the intake. Reinstall. 15 minute job.

I have no clue on the seafoam stuff, never used it. I am talking about fuel injector cleaner. I've read some weird stuff up here about Jeeps running funny after seafoam treatment, it maybe very good stuff, Idk. So for misunderstanding, let me mosey back over to the tj section before I get jumped!

Red Line makes a very good fuel injector cleaner which also contains an upper cylinder lubricant. Dump in a bottle just before an oil change or you can add 1.5 ounces per 10 gallons of gas as a maintenance dose, that's after an initial 1 bottle cleaning.

The "box" is the throttle body. It is held on by four bolts. The electric cable for the throttle by wire also needs to be unplugged. You get to both of these by removing the air intake tube that is connected to the throttle body. That is the full extent of what need to be removed.

I was talking about the electronics on the side. If its part of the TB--ok--I thought it was a separate component.

Just read through a good thread on another forum. Some said "not to mess with the DBW TB, and there really is no reason to clean it" most of their TB's were not all that bad to actually need a cleaning. If there is a lot of buildup, the owner is doing something wrong I.e not replacing filter or using a K&N oiled filter (like myself)

Mines not too bad (yet) I am going to look into an AFE dry filter to replace the K&N on my Banks system, will see.

Thanks for the info

If your injectors are clean already you can just put a can of 44K in the tank every oil change and you'll be good.

Ok, so I used the throttle body method and it worked great. I also added some seafoam to the crank as a flush. When I changed the oil, there was soild dime size carbon deposits falling out. It worried me a bit at first, but when I started it and drove, it felt like a whole new machine.

Is it normal to have that much blow-by on these?

I've been using seafoam for many years

oil to keep sludge from building up/remove existing sludge

gas to clean injectors

in throttle body to clean out carbon build up

I may very well be mistaken, but a fuel injector cleaning just sounds like a ripoff to me . . . I have a mental image of a mechanic pouring some injector cleaner into the tank then charging $60.00 . . .

That's the quick lube injector cleaning. A real injector cleaning uses a machine that forces a highly concentrated cleaning agent through the injectors under pressure and actually does something. The problem is that most injectors don't get dirty enough to need it, so all you really need is something in the tank once in a while to remove anything that does happen to form. The biggest problem with dirty injectors is crap that builds up in the inlet screens and the only thing that will fix that is to remove them and dig the crap out.

My mechanic recommends a can of SeaFoam in the gas every fifth tank and half a can of SeaFoam through the vacuum line every oil change. That's what I do with my Trailblazer and after the first couple of treatments, my mileage increased 2mpg. It was getting 18.5-19 overall and now it's getting 20.5 overall.

It was suggested to me to occasionally use Sta-bil as preventative maintenance.

Is it best to add Seafoam to the gas tank with a fresh full tank of gas or is it OK to add it to half a tank?

The only negative I have ever heard to using the vacuum line method for cleaners is that huge plume or smoke you get when you start it back up and what it may be doing(clogging) to your O2 Sensors mounted in the exhaust stream.

I try and use only good clean gas and use Seafoam in the Gas tank every few months.
But mostly for its stabilizing/water eliminating value vs cleaning
