Could you elaborate on the bored out throttle body? I have a 04 with 4.0 and
am looking for ways to increse the milege. Just finished the air cleaner,
electric fan, and exhaust ( cat back ) upgrades, but havent gone anywhere to
check milege. Taking a trip next week to see.
Thanks Tom

It's just the stock 4.0 TB that's been oversized. The end result is
it will flow more air. This of course does no good at all if the
rest of the system (intake rail, head, exhaust system) can't flow
that much.

Of course Hesco is't the only place to get one, and it is possible
to make one yourself (if you have milling tools).

Likely a drop in fuel pressure when it sits for a while. If it starts
immediately when warm, this is probably it. Leaky fuel injectors or
check valves in the fuel return line or regulator (depending on design)
are suspect. A worn out fuel pump will also cause this.

Some makers during some years program the PCM to delay the ignition
system for a few revolutions of the engine to help circulate oil into
the top end of an overhead camshaft setup before allowing the engine to
fire. I seriously doubt this design applies here, but I think it's a
good idea no matter. AFAIK, DC does not use this logic in any of their
cars.

Great fuel mileage isn't something you'll see featured on a Jeep
product. They're heavy trucks with engines of vintage design; my TJL
weighs nearly 2 tons empty, and around town I manage 18 mpg, and about
20 on the highway. Driving habits and proper tire pressures affect this
the most. I'm perfectly happy with 18 mpg; most of the 4WD Chevy-guys
around here average 6-8 mpg. around town; one Expedition owner I know
averages only 4 mpg! I used to own a crappy old '68 Dodge Polara 440
that only got 3 mpg, city or highway. You could do worse.

bllsht

A bored out t/body will do nothing for fuel economy. It won't help
performance either, other than at wide open throttle.

It goes without saying that if you're "enjoying" your "performance
increase" from a larger t/body, you're not gonna get any fuel mileage.
