Oh, and we need some new videos of your WJ!!
Let me say Bruce from F&B is fantastic. My throttle plate has bent twice from the boost and they replaced the plate with a stronger one.

I'll try to get some videos as soon as I can.

Re: What are you doing to your WJ next?

Wow, there must be some serious pressure going through that throttle body, the plate isn't exactly thin on these! I certainly won't need to send mine in for this upgrade anyway.

Look forward to seeing some clips of the beast!!

Re: What are you doing to your WJ next?

finally caught a break around work and the heat in the NorthEast to swap the door lock actuator on my drivers front door on Thursday evening. Now just gotta wait for another hot day to make sure this 1 will work better. LOL. The process definitely went smoother with a torx set. I had to get it done after not being able to open the drivers door from the outside during the day on Wednesday and Thursday. haha

Re: What are you doing to your WJ next?

Well this afternoon I had a little play with the throttle position sensor. When I plugged the datalogger in and monitored the TPS it would range from 8% (idle) to 75% (WOT) which I found strange. So to rule the F&B TB out I temporary put the sensor in the OEM TB and it ranged from 13% (idle) to 80% (WOT), then I tested the sensor on its own- ranged from 6% to 100%. Can't figure out why it isn't reading the full range on the TB.

After that, I installed a revised tune supplied by Ryan last Wednesday. Look forward to going to work tomorrrow. Can't believe the extra MPG I'm getting either, with the stock PCM I got 18MPG max on a run, now....


Actually read 22.7MPG at the end of a 90 mile highway only run, that is with some round town driving too. No doubt it will be back to 14MPG soon.


Think I found my power steering leak too, the pipe can be wiggled around and it looks like there is some fluid in the gap. Cleaned it up with a paper towel so if it gets grimy that has to be the source. Is this the pipe that got revised (sits just to the left of the reservoir and comes out the top of the pump?

Yes, the pipe and fitting got revised in 2003 I think. It took me 30 minutes to replace mine, just unbolt the pipe from the pump, and from the bottom of the fan, then bolt on the new one and you should be good to go! It can be tough to get that fitting off the pump, but a little elbow grease and I got it to pop off.

Re: What are you doing to your WJ next?

Epic, that is the reason why I love this forum and all it's members. Freaking excellent advice always on tap.

I might actually do this myself rather than getting the shop to do it, heck gotta start somewhere! Do you know where I can find the part numbers for this stuff, had a look on WJJeeps.com but can't find a power steering section...

Re: What are you doing to your WJ next?

Glad to help where I can! Check out this linky to Just For Jeeps, this would do the trick. Not too bad to do yourself, unless that connection is stuck on good. Mine was, but with the right wrench and some force I got it to pop off.

Re: What are you doing to your WJ next?

Excellent, thanks again. I'll order it from the dealer since shipping + taxes would probably work out the same as the part!

I'll give it a go, if all else fails, the shop is less than 1/2 mile from my house.

dealer should definitely have the right part, thats where I got mine since I needed it right away before a long trip. Good luck!

Marty check this out in case this happens to you. Replacing a power steering pump on a 4.7L

Re: What are you doing to your WJ next?

I had no idea you were seeing that kind of improvement on your mileage. I'm impressed.

You may have to enlarge the TPS bolt holes to "advance" the TPS so it has the correct voltage (throttle position) at idle.

Re: What are you doing to your WJ next?

Dave; your post just made me re-think about doing this job myself. My pump is working fine and I sure as heck don't want to break it!

Ryan; yeah, saw a few posts from Dodge guys doing that to the TPS after you mentioned it a while back. I'll need to have a play with a multi-meter to check the voltages on it prior to drilling.

Should have said about the mileage actually, I'm stunned. I had cruise control on at 65 for the majority of the trip, say about 25 miles was between 30-40mph. Even more surprisingly, on my little trip to work each day I'm getting 19.3MPG.
