What did you do to your XJ today

Today I pulled my RV to the dump station and back. It has been in my yard since the sand flea rally. Well now it's back in my yard. O and I washed it.

Picked up about 4mpg... only thing I did was 1. removed silencer-baffle thing from air box 2. moved air temp. sensor from intake manifold to airbox 3. raised rear of hood to allow underhood heat to escape... 4. installed turbo muffler and ixnay'd the cat (no DEQ here!)... after 6 months averaging 14.7 mpg, this last tank netted almost 18mpg! Wow... didn't change driving habits, gas, anything else... just those 4 things above...
 
Dang it! I hope you are wrong!

You will find that most people who post information as clearly as John did that it is usually acurate. John is no exception to this rule!

1. This is counter intuative to everything I have learned about vehicles, particularly XJ's.
2. Put the Cat back on. unless it is blocked it won't make any difference to your gas mileage!!!!

? Put the gloves away ;)

I appologize if I came across with gloves on (I don't fight with gloves;) ) that wasn't my intention. Maybe I was in a bad mood, maybe just a pet peeve? Not my intention.

My comments (only my opinion) still stand. :kissyou:

LOL No offense taken. I did not have my coffee yet either :) Hope: is a belief in a positive outcome related to events and circumstances in one's life. Hope is the feeling that what is wanted can be had or that events will turn out for the best.[1]
In a religious context, it is not considered as a physical emotion but as a spiritual grace. Hope is distinct from positive thinking, which refers to a therapeutic or systematic process used in psychology for reversing pessimism. The term false hope refers to a hope based entirely around a fantasy or an extremely unlikely outcome.

Um, no... the cat will not be going back on... the ceramic media inside the cat (i.e. the "catalyst") had broken away from the casing into several pieces and was just rattling around, causing a restriction... second, I had a local muffler shop do a backpressure test on the exhaust system... before replacing cat and old stock muffler, bp was almost 6 psi... way too high to be considered functional... after replacement, bp went down to around 1 1/2 psi... perfect for an otherwise stock 4.0... if we start getting DEQ checks down here, I will go with a low-restriction cat...

EDIT: wasn't MAT sensor... moved IAT sensor... Intake Air Temp. ... moved from intgake manifold to air box...

I forgot to mention to him, the wheels were coming from my 05' unlimited non-rubi.
Another previous ride... after the 08 4dr JK and the 09' 2dr JK. for those that don't know me I've come back full circle to another TJ/LJ Unlimited.. this time the price was right so I got the Rubi in an 06'. So if Believe & Recieve seems confused, it's totally acceptable around all my Jeeps lately. :-)
And that XJ on 31's, John has and also Jimmy's. They have me thinkin'...!
Well, for a moment anyways.. nice rigs...

So there IS more to the story.
Hense the reason for my comment:

Now that we have more of the story, your original post about your mpg makes MUCH more sense.

Since we have made up :kissyou: and you seem like the philisophical (sp?) type....... I understand what Hope means. What I suspect you failed to consider is what the "Hope" that you were looking for would mean in the way of consequences for the opposing party. :soapbox:
