    Replacing HVAC vacuum lines behind the dash

    no, not yet - I've been waiting for the mechanic to have the time and space to do it. I have just moved house and now have space to work on the jeep so I may have a go at this over the holiday break.

    Replacing HVAC vacuum lines behind the dash

    The mechanic pointed out where they found the leak, this is behind the glovebox (remember it's RHD) in the first pic you can see the hoses coming from the control panel appear to be ok, but the hoses heading back are chewed - the brown one is definitely missing an inch or so but it's hard to...

    Replacing HVAC vacuum lines behind the dash

    Hello from Australia, where we all drive on the wrong side of the road while sitting in the passenger seat! (Just my way of saying we are RHD :) ) I picked up a nice looking 2003 model recently, but turns out beauty is only skin deep and it has issues. One issue is the ventilation only blows...

The differences in controller and firing rotation would also...

    Hi! My 2004 TJ has the older style OPDA which appears to have a bit of a tapping noise. The mechanic is recommending replacement and suggesting it would be better to go for the Crown version from a 2005 - 2006 model, but I can't find a definitive answer on whether it will fit or even if there is...

    Do O2 sensor errors affect performance / economy?

    @Wranglerfix I think they were called Solo Auto Electronics or Solo PCMS.. I'm not sure the PCM is failing, I think it was programmed to expect 4 sensors and after reading all the O2 sensor posts saying you have to use the NTK parts I'm wondering if I should try replacing the Mopar items with...

    Do O2 sensor errors affect performance / economy?

    Hello from Australia! I have a 2004 4.0L that keeps getting P0135, P0141, P0155, P0161 errors. I keep clearing them with an OBD scanner, but within a few days they are back. Do these errors affect the PCM in any way? Would it cause poor economy? Often when it is cold started it smells like it...
