mars81 OK So I've been fighting with this damn things and I can not get them out to save my life. I've doused the things with PB plaster and still nothing. I just want seem to put enough force on the socket. Does anyone live in NoVa and have have a set of jack stands that I can use? Having all four tires on the ground just isn't giving me enough clearance. I'd love to just go out and buy a set but I live in a small apartment and don't even have enough room for what I have as it is. Any help would be great! Thanks

mars81 OK so good and bad.
Good: bought the front pair on advancedauto.com (extra 15% off for buying online and just choose pick up at store) for around 85 bucks. Plus they throw in a $10 rebate for each one and a $25 off $50 on a later purchase. Great deal. And they lend the 3 piece socket kit for doing the job.
Bad: can't get those damn things out. Tried it cold, nothing. Tried it hot, nothing. I'm going to get w can of pb blaster and see if that does the job.

So if anyone is thinking of doing it, get on it now. And if anyone has a better way to remove them let me know.

Nope. It should be tall enough to keep all 4 tires on the ground.

ChaddG I put a k&n filter in, and put the soft top on, went from 14 mpg to 15. I will try the o2 sensors

Bielzebub I use MFA Super Unleaded fuel in my 99 with the four banger. In the city I usually get about 16 to 18, and highway, well I don't drive highway for very far, so it's tough to estimate. I know that I can drive around town for about 4 hours and barely use 1/8 of a tank.

I work at homedepot and 90 percent of the lawn mowers that are brought in for servicing are because of "bad gas" or a fouled carb because of the ethanol content. Sta-bil works great for small engines.

yep the pre-cat are air/fuel. I'm glad i don't have to worry about 4 O2's. My 97 just has 2. 1 upstream and 1 downstream.

mars81 So new plugs installed and it helped a bit but not much. As for the O2 sensor...since there is 4 of them, a certain one I should start with or is there a way to check the sensor?

That's a sure sign that you have a rich mixture and a problem in the system somewhere. Poor fuel mileage can be caused by several things. Replacing plugs, plug wires, O2 sensors, air filters, and other things in the system are always a good idea and a great place to start. Especially if you don't know the age of the components. O2 sensors are relatively inexpensive when compared to the possible savings in fuel costs and are somewhat easy to replace. My '98 2.5 manual consistently gets 20-22, but I drive it like a grandpa (which I am).
I couldn't have explained it better.

PStov98TJ That's exactly what I was talking about. Used it to find stations by me in South MS.
02-20-2013 11:02 AM
mars81 So I searched and found this website... http://pure-gas.org/index.jsp in case anyone wants to search. But nothing in the DC metro area.

mars81 Yeah I wouldn't even know where to find non ethanol gas. Everywhere I've lived has only had the <10% mixture. I just bought some new spark plugs...now I just need to borrow a torque wrench and I'll let everyone know how it turns out.

Same here! My Jeep gets probably 1-1.5 mpg better with non ethanol. That E-10 crap is not really good for the TJ engines anyway (not bad, just not good either). My Jeep runs a little smoother with the non ethanol as well. It costs a little more but it's worth it to me. Just a thought.

Pit Bull Getting about 12.5 mpg combined here. I know why though..... I am running 235x70x15 tires on my 98 Wrangler Sahara w/ a 4.0, auto trans, and 3:73 gears. It has a 2" bb lift and once I get either some 31's or 32's on it..... maybe even some 33x 9 or 10.5"s x. 15..... if they will make them again, my mpg should go up a bit

mars81 Actually yeah just did that. Haven't really had any reason( or time) to open it, so when I was out walking the dog I went down to the garage to take a loom to seen if they were OEM or not and there was nothing there lol. My old YJ had them

You might want to open your hood. You don't have a distributor cap, or spark plug wires.

tonyb11 im also havin this problem. i jus picked up a 04 rubicon and i know its gear a bit lower then my last sport but it seems pretty bad on gas and i baby it on road.

mars81 How could I test the O2 sensors? How many are on the 4.0? I haven't thrown CELs to the read codes.
02-20-2013 01:17 AM
InvisiblePants It could also be failing O2 sensors.

mudmagnet63 Yep the toad got about 18+ on our trip to CO. last year with 31's and 3.07, not sure about city we dont even have a stop light here.
02-20-2013 12:58 AM
duaneduanet Yea something is wrong. My 1997 TJ 4.0 gets 17.5 city. 3:08 gears

PStov98TJ I know what you mean. But even accelerating as fast as the other cars around you will knock it down. But not that much... Might want to have it checked out. Change your spark plugs out. Changed the oil lately?
02-19-2013 11:59 PM
mars81 I definitely don't granny it but I'm also not redlining the tach off every light.
02-19-2013 11:57 PM
PStov98TJ How are you driving it? I get like 15 city and 16-17 highway with the 4 banger, 4.10s, and 33's.
