Re: Horrible, I mean really bad, mpg on my hemi

uuumm awd/4wd certainly does help handling on pavement... the trick is go in a little slower so you don't understeer and nail it... as long as you can handle a little 4 wheel drift you'll smoke an equivalent equipped 2wd everytime... I used to drive audi quattro's and those things where amazing in the corners once you learn how to do it shocked mustangs and camaro's all the time when i went around them in the corners...

Your audi wasn't 4WD is was AWD is is most of the time a 2wd unless power is needed up front to maintain forward momentum. trust me, I know how the Quattro system works. secondly Camaro's and stangs are not that great in a corner. also if your 4wd and going in a little slow, there should not be a 4 wheel drift, and 99% of race cars are 2wd because of the handling characteristics

I did a seafoam treatment and replaced all the fluids with synthetics. Which sensors should I replace. My plugs seemed ok when I pulled them for a compression test.

Yes a lot of race cars are 2wd, but remember your in a jeep so your center of gravity is way different. In a front engine suv with 2wd you are way more prone to your rear end sticking out during turns. I have a 98 grand cherokee with selec trac so I can switch between 4wd and 2wd, and on turns 4wd does better. If you take too fast a turn in 2wd, you will roll over, and you can probably get away with making that turn in 4 wheel. 4wd also gives better launches out of turns . Btw this was a gas mileage thread, but I love this debate.

ive driven mine hard into and out of corners and never had the rear step out, only done that on wet ground.

Well that's because you haven't experienced the difference first hand, but there is a difference.

maybe, but I don't push it too hard in the corners cuz the suspension is still stock, aside from tires (wheels and tires stolen this week), and brakes, the suspension is stock, and my driving style prefers the rear to be somewhat loose

Re: Horrible, I mean really bad, mpg on my hemi

It is senseless to debate this; drive one that corners and you will be humbled very quickly. Even when new the stock WK suspension is terrible at cornering. Considering that these suspensions get worn out in as little as around 40k miles, your 2WD is a marshmellow needing new shocks, springs, isolators, sway bar bushings, and end links. An upgraded suspension like mine is a totally different vehicle than a new stock WK, and corners hard, under total control.
All 4wd systems are not alike as well. The QDII system is very advanced, has front and rear limited slip differentials along with a ltd slip transfer case, so it will transfer power to the wheels with the most traction automatically. 100% of the power can go to just one wheel if that is the only wheel with traction. In a rainstorm, I can floor it from a stop and it will just fly with no wheelspin. Your 2WD has an open differential, the worst for cornering.

Do you mean a low gear transfer case? I don't think a limited slip transfer case exists. How are your konis? Debating whether to get the konis or the srt oem bilsteins

Re: Horrible, I mean really bad, mpg on my hemi

Im gonna stay on topic cause ive been looking for better mpg's for my 6. I replaced the MAP sensor, TPS sensor, and IAC valve sensor. I noticed a huge difference in shifting, power and overall driveablity. so maybe start with those. i did sparks as well. only problem im having is the IAC doesnt seem to hold the rpms well when cold but idles and performs great when hot. I got the part from auto zone and its a duralast part. Duralast/Idle Air Control Valve (AC356) | 2005 Jeep Grand Cherokee 4WD 6 Cylinders K 3.7L SFI SOHC | AutoZone.com

Now this is my second one and the first one didnt even keep the car running! my original problem was low idle which is fixed with this part, but the idle is not steady, WHEN COLD, as well as a few other weird things. Dont get that part. i dunno if anyone else had this issue. Oh yea and when i put the old IAC back in it started better and high idles perfect, i dunno.
