    P0172 p0175 engine overheating on idle

    Agree. If coolant old, flush properly, check heater core lines. HEAT ISSUE - I needed to reverse flush my daughters heater core twice as it got plugged up. Do this before adding new coolant. Is thermostat ok. Sounds like time to replace with OEM thermostat as I hear many after-markets fail to...

    Nephew bought a Liberty 2012 It won't charge

    Clean every ground, and reinstall. This takes care of simple problems. Old cars develop crust on ground straps. Measure voltage out of alternator and compare to battery. if alt voltage not getting to battery, then I would suspect internally corroded wire. this is a real thing.

    2005 Liberty Sport

    Due to having 20 year old wires, I wonder what is the voltage at the bulb. Please measure if bulb voltage == battery voltage, or is there a drop. If the bulb voltage is lower, that helps explain poor lights and you should install a relay taking the power off the battery directly. Fuse this work...

    clunking noise up front

    It is best to have axel off ground just enough to get tires off then spin shaft and wheels. You feel and hear the slop better when wheels are not engaged to earth with a load. good luck.

    2010 Jeep Liberty front wheel droning noise

    can you pull the front shaft and see if noise continues? This would tell you something. Looks like the garage gave you new parts which were not worn? At least you will not need change those parts again soon (we hope)

    06 Jeep liberty wont turn on

    I suspect the fuse issue was corossion and dirt not dead fuses. In the past I have removed ALL fuses and cleaned the terminals and re-inserted them. THIS IS DANGEROUS as you can introduce a new problem you never had before. I am willing to do this in the garage, slowly and carefully. I also...

    P2311 - 2008

    Did you verify voltage from ECU to the coil. If coil does not get voltage, spark plug gets no voltage. Just a thought. Never hurts throwing new plugs in as they will eventually need changing, but probably was not needed. You introduced a SECOND VARIABLE, new plugs and new coil. The fewer...

    Smart to use a driveline shop. They should do it all properly, as opposed to others who may not.

    Clean and run them or replace?

    Low oil pressure at idle concerns me. I assume this is "after" new oil and filter. Double check with mechanical oil pressure gauge before "fixing" anything. could be sensor. I assume old oil is/was OK and acceptable old oil. I am going to assume low oil at "normal temperature" and idle and...

    Clean and run them or replace?

    Do not forget to drain and fill axles. You never know what the previous person did and how much water is in axles. Catch old fluid when draining and if clean and new, reuse. This rarely happens but with oil at $10-15 quart, well work catching it. Do BNOT assume plugs ar pre-gapped. Use...

    Intermittent fault.

    Temperature if 30 minutes later it starts or runs. Yes temperature can kill a sensor, and this is a cheap and easy item to replace, so maybe it is ok to throw parts at it. Could be plugged fuel filter and or pump issue. Think heat. Once the engine is warm, the ECU uses fuel trims as opposed to a...

    Need advice - unexplained missfires

    Did it run after assembly and then 1 week later problems, or are these problems after re-assembly? I doubt it is the PCM because of coincidence. You did lots of stuff, then issues, with same PCM. Doubt if you lost 3 injectors at same time, so I doubt 3 injectors are clogged up with dirt at...

    sudden Catalytic Converter blowout?

    I agree. Tap on the cats with a rubber hammer. Get dirty. Watch a u-tube video on how-to. Could be dead after 18 years, I do not know how and where yu drive (sea water, deep rivers), so I assume nothing.

    Help - how to diagnose a bad catalytic converter?

    The vacuum system is easy to diagnose using a hand vacuum pump. You can rule out canister, lines until the last thing (always the last thing) does not hold vacuum or else solenoid does not work.

    Help - how to diagnose a bad catalytic converter?

    For the P0456, time to tighten the clamps, and if possible replace the rubber hoses in the evap system. You could do proper testing of sub-components with a vacuum tester/pump thereby reducing what it may be / is. If you can rule out some components, then you will by definition find the faulty...

    Help - how to diagnose a bad catalytic converter?

    Mileage says it is time to replace the cats. I hate wasting money buying the wrong part. You WILL need to change the cats soon, so if finances allow, maybe now is a good time. ANYBODY OUT THERE HAVE SAME SET-up aND WANT TO DO A TEMPERATURE GUN TEST FOR ABOVE AND POST PRE AND POST CAT...
