    03 Liberty Limited 3.7-Bad Mileage

    I hand calculated the mileage as well. It was about a 19.5 average round trip, which isnt bad at all. I think I also spent less than $60 in gas the whole trip too, so thats a bonus.

    03 Liberty Limited 3.7-Bad Mileage

    I drove it to my parents and back over thanksgiving. (approx 300 miles round trip). EVIC said 18.4 on the way down (mostly downhill driving) and, at one point, 20.6 on the way back! And that was on Sheetz (in Pennsylvania) gas both directions. (Although I have heard they don't have a "specific"...

    AutoXSS: The 5/16 line next to the firewall was almost split entirely end to end. I replaced that and hopefully everything is ok now. THANK YOU for giving me an idea where to look.

    Also, i heard what sounds like either a hissing, or possibly a sucking sound coming from under the drivers side near the front of the car. I assume this is a vaccum leak, correct? I have looked under the car before and seen a rubber hose connected to steel line on the frame that looked cracked...

    I haven't had this car out on an hour or two trip. Hopefully soon. I have one about 1/4 mile or so stretch of road on the way to work that I open her up briefly on, but thats about it. I dont drive like grandma either, although my passengers wish I would. The EVIC said about 9 this morning. I'll...

    03 Liberty Limited 3.7-Bad Mileage

    Its back to doing the same thing again. Mileage is about 8MPG or so. Horrific mileage. Its got New plugs, New Air filter, new PCV valve, passed a bottle of Techron through it on the last tank of gas. Not really sure what else i can try, or that I am missing. I think partially one of the...

    03 Liberty Limited 3.7-Bad Mileage

    The mechanic replaced 1/1, and 2/1. Seems to be getting better mileage. I also changed the PCV valve, and fixed the leaky passenger side valve cover gasket, and put a new air filter in it. got about 15.6 or so on the highway and about 13.5 in the city. I still would like to change out the spark...

    03 Liberty Limited 3.7-Bad Mileage

    I just called the mechanic. He said hes going to diagnose for about $65 to make sure its definitely an o2. And then about $100 to replace the 1/1 sensor. I told him to go ahead and replace 2/1 as well (if 1/1 went, 2/1 probably isnt far behind, right??) So looks like about $265-300 or so... fair...

    Tommud: I was almost positive you had 4wd, why else would you be here, right?? It also had previously thrown the p0455 large leak code. I replaced a short elbow line on the canister, and the code hasn't reset yet. I can apparently command the EVAP test to run with my scanner, but it hasn't...

    03 Liberty Limited 3.7-Bad Mileage

    Thanks guys. I'll have to try that procedure tonight. I have also heard that the upstream o2 sensor can cause all kinds of hell if its bad, especially if its the 1/1 sensor. My problem is that it seems like a difficult one to remove. I did 2/2 by myself, but that one was easy, other than getting...

    03 Liberty Limited 3.7-Bad Mileage

    Hi renegade. Not really positive. Only had her about a week or so. I think its about 155 or 156K. Is that relearn something that can be done at home? I remember seeing somewhere a procedure like disconnecting the positive and shorting the positive to ground to clear PCM memory, and to force it...
