great video very helpful however the sensor on the rear of the manifold is the air intake temp sensor (IAT) NOT the mass air flow sensor.

@dungeonmotorsport 12 жыл бұрын

Allows the engine to breathe easier. With that you get better fuel economy. I haven't thrown it on a dyno, but I can tell you that between this and the K&N Cold Air Intake, the Jeep is much more throttle responsive, quicker on acceleration and has a slight increase in intake sound. Highly recommended if you upsize the tires.

I just wanted to thank you for putting up this video. I've done minor fixes forever. Found you more out of necessity as I was told my throttle body needed to be replaced and was given a very expensive repair estimate. I watched your video several times and I did it! I bought my own tb and replaced it. Still have issues with it relearning. Will see what's up with the obd but Hubby was impressed. Love my Jeep and want to keep her going as long as I can. Wish I watched spark plug video before putting it back together tho. 😕😆

Excellent informative video Just ordered a new modified TB from Fastman. Pretty sure the install will be the same on my 2008 Jeep Commander Sport 3.7L. Looking to get a little more launching power. Hopefully this combined with my drop in K&N high flow filter will give me the little boost im looking for.

Where in the h e double hockey sticks is IAC located on this throttle body? I'm guessing under the cover on the left side but don't want to tear it apart and messy up my day in a big way.

I'm wondering about how to reprogram those. I understand they require that with a new unit placement. I have a cable controlled unit and am wondering if that applies if I'm just removing, cleaning, and reseating my original unit.

@XTRABIG 3 жыл бұрын

Thanks. Going to replace mine. I keep getting a code indicating a IAC problem. However my late model 2007 3.7L uses a 2008 Throttle body just like in this video so there is no IAC valve. One last point the new Throttle body must be calibrated

@dungeonmotorsport 4 жыл бұрын

Butt dyno says yes. When paired with a cold air intake it has more top end breathing and requires less throttle input for normal driving. I also noticed about a 2mpg highway increase after installing that combo.

You don't need to remove them screws on the air box it just pops on an off with a little bit of force.

I noticed that you didn't change the gasket for the throttle body. Wouldn't it make sense to do that? In case there's something wrong with the old one. It's not hard to do and the new throttle body should come with a new one.

@JonRoc Ah, nice! Feel free to post back on how your install went. My specific "TheFastMan" throttle body took about 3 weeks from order to delivery. Keep that in mind when trying to schedule installation. Dan, the owner, is an awesome guy - very friendly to deal with. Top notch customer service and his prices are reasonable. I would do business with him again.

So, is the outside diameter of the Fastman throttle body the same as the OEM? I heard that you can do the same thing cheaper by grabbing a throttle body from a 4.7.

I have the same type but an 07 and have been experiencing coldstarts that has the RPM jump to 1700 even when its 80 degrees outside, could this be a Throttle problem?? Horsepower is lagging as well. and when warm, car will not exceed 60mph, when i press on the gas, the rpm shoots from 2000 to 2300 easily and with no gain in speed. What are your thoughts??

I deff uped my tire size so my wk sometimes is a little sluggish to switching gears or feels a little to heavy so deff looking forward to getting a better throttle response great diy though!

@dungeonmotorsport 10 жыл бұрын

In the meantime, feel free to disconnect your battery for about a half hour so it can relearn rpm shit points with your new tire size. You should notice a difference in about a hundred or so miles as it learns those uprated tires.

I did it last night so I'm hoping it changes but I heard a Dino could help what are your thoughts on that?

Cool. Yeah, a proper tune would definitely help, especially if you've done exhaust mods too.
