      Retrieve any codes that are stored in the computer and report them here. Alternatively , you can search that code on google and see what may be causing it.

      Ignition misfire may be caused by the following:
      Fouled spark plugs
      Faulty spark plug cable
      Faulty ignition coil/coil pack
      Faulty ignition control module
      Faulty rotor/distributor cap assembly
      Burned exhaust valve (in which case you would likely have backfire)
      Clogged/faulty fuel injector
      Worn piston rings (low compression)
      Blown head gasket or warped cylinder head
      Cracked engine block
      Cracked piston
      Bent pushrod
      Loose rocker arm
      Collapsed hydraulic lifter
      Worn valve springs

      These are only some of the possibilities. I've lists the most common causes of misfire (concerning a single cylinder)

    I haven't started my vehicle in 2 yrs, and dmv requires a smog certificate. What should I do to begin this process?
    Charge battery? Reboot the computer system? (Hand held code reader) Add a liquid into the gas line? Run vehicle for a half day?

      Charge battery or replace to be safe if it ran good before you let it sit then its still a good car get some fuel treatment to clean old gas depending on your fuel system its mite start up with a little pumping on the gas turn the key all the way but not to start just to get the fuel pump ready on and off a few times then start or you may need a can of starter fluid, the vehicle computer will program itself after you drive around for 30mins-1 hour good luck

      I failed smog test because of the moniters.
      Two (moniter readings) never booted/responded for reading, though my LR passed
      All the emissions. The AAA service jump started the vehicle but didn't charge the battery.
      So I was forced to drive around for the alternator.

      Here are the codes (p1536 & pO560) SYSTEM voltage?
      Dmv will not give me a registration until i pass smog,
      and it will not pass until the moniter reads correctly.
      Now im in for an interesting process of events...huh?

      the battery mite be dead it mite be the issue for the code P0560
      P0560 - System Voltage Malfunction

      Possible causes

      - Loose or missing alternator drive belt
      - Faulty alternator
      - Battery defective
      - Open or short system voltage circuit
      and the other code p1536 mite be your Parking Brake Switch

      So check batt for full charge.
      Check the alternater belt drive for firm fit?
      Basically... just take it to the mechanic, or have one check for these issues?

      you may need to let your computer program more and boot all systems some cars take longer then others a obd2 is a good tool to know when systems are ready I don't think the codes failed emissions ,if you have a fair mechanic and want to fix the code issue sure they should be really minor if you can't check the Possible causes your self tell them to check them ,also next time you go to do the test ask them if they can check if your systems are ready

    Vehicle fails to retain charge, discharging a fully charged battery within a hour. Occurs about every two weeks.
    Mileage 80K. Occurs in hot or cold. No faults found by dealers. Usually preceded by proximity sensors not working/coming on at random.

      You may have an intermitent draw on the battery. I can't imagine why the dealer can't find anything.
      Did you mention the proximity sensors coming on at random?

      You'll have to be more specific. Do you mean when you turn the key to start it does nothing?
      Or is the engine cranking over well and not starting? Let me know and I can help you better.

      No real accurate method - as a consumer - to know the answer to this question of a particular year, make and model repair history. How many miles are on the vehicle in question?

      There are several websites that may have owner surveys and feedback provided; www.consumerreports.org, www.edmunds.com, www.kbb.com, www.carsurvey.org - to list only a few.

      Typically, the water pump, radiator, and hoses / thermostat should last to around 100k miles - before needing replacement. This assumes of course, the cooling system is maintained previously with regular coolant changes and system flushes per the vehicle maintenance manual and recommended service guidelines.

      Check the many on-line auto parts sources, such as; www.autopartswarehouse.com, wwwpartsgeek.com, www.autoanything.com and www.rockauto.com - to list only a few sources. For example, they (Rock Auto) list the water pump from around $46.00 for your vehicle; Uro parts # UTC 34378 (includes gasket).

      The water pump or radiator is easily replaced, refer to the 'How-To-Guides' feature on the AutoMD website, or the repair help website at www.autozone.com - as just two examples.

    How to check for clogged radiator and proper water flow
    changed thermostat and water pump as well as leaking hoses

      Make a careful visual inspection of the entire cooling system, and then pressure test the cooling system and radiator cap. A pressure test will reveal internal leaks such as seepage past the head gasket as well as cracks in the head or block.
      Possible leak points include hoses, the radiator, heater core, water pump, thermostat housing, head gasket, freeze plugs, automatic transmission oil cooler, cylinder head(s) and block.
      An intact cooling system should hold 12 to 15 psi for 15 minutes or more with no loss in pressure. If it leaks pressure, there is an internal coolant leak (most likely a bad head gasket but possibly also a cracked cylinder or engine block).
      It is important to pressure test the radiator cap, too, because a weak cap (or one with too low a pressure rating.
      If no leaks - either internal or external, then there are a few possibilities for any overheating. Clogged or dirty radiator passages, faulty thermostat, clogged radiator hoses, clogged heater hoses, clogged heater core, radiator cooling fans not working.
      Test for clogged radiator would include visual; remove the radiator cap and observe the coolant. By flow test - check the coolant flow through the radiator passages and looking (feeling) for hot spots on the cooling fins. Use the pressure test also to determine if the radiator tubes are clogged.

      I have replaced hoses,thermostat and water pump on this. You can't use device for this type of vehicle , no radiator cap only res.cap.I can see water in the thermostat and hoses get hot ,but real hard on squeeze test. Person who owned it cut heater hoses and pinched them off really at a loss here. thks

      A very simple flow test to perform (with the radiator removed) is to place the palm of the hand over the lower outlet and fill the radiator with water, then remove the hand to measure the water flow; it should empty very quickly on a radiator with unobstructed fins / tubes. If it drains slowly, then it has blocked / partially blocked tubes.

      Cost of a replacement radiator is inexpensive considering its service life at 11 years. They are priced mostly around $190.00 from various auto parts sources on-line; www.autopartswarehouse.com, www.partsgeek.com, www.rockauto.com and any local auto parts sources.

      Use the AutoMD 'How-To-Gudes' feature for generic steps to; test the cooling system, and replace the radiator along with other system components. There is also the on-line resource at AutoZone for more specific maintenance instruction and details by vehicle and model.

      Sorry, I do not have pictures of connectors and the sequence of colors but I can tell you what color wire goes into what pin number. The connector itself if looked at close with magnifying glass should be numbered 1,2 3. That being said..

      Pin 1 = Black / Yellow
      Pin 2 = Pink / Black
      Pin 3 = Black

      Loss of coolant because of a coolant leak is probably the most common cause of engine overheating. Possible leak points include hoses, the radiator, heater core, water pump, thermostat housing, head gasket, freeze plugs, automatic transmission oil cooler, cylinder head(s) and block.

      Make a careful visual inspection of the entire cooling system, and then PRESSURE TEST the cooling system and radiator cap. A pressure test will reveal internal leaks such as seepage past the head gasket as well as cracks in the head or block. A good system should hold 12 to 15 psi for 15 minutes or more with no loss in pressure. If it leaks pressure, there is an internal coolant leak (most likely a bad head gasket but possibly also a cracked cylinder or engine block).

      It is important to pressure test the radiator cap, too, because a weak cap (or one with too low a pressure rating.

      Note: do the radiator test while the engine is cold.
      Obtain a loan free radiator pressure tester from the local auto parts stores such as Autozone, O'Reilly or PepBoys. Follow their instructions and pump it an adequate air pressure 12 -15 psi or the allowances on the radiator cap. Observe the leaks and perform the repair.
      Note: do not OVER-PRESSURE than the pressure allowed in the radiator cap.
