    Just replaced serpentine belt and upper idler..Belt too hot to touch after 5 minutes

    Why does my engine fan run continuously while the car is running and 5-10 minutes after it's shut off?
    The engine fan only started doing this recently. The engine fan only came on occassionally before then. Now the fan comes on and runs throughout every single use of the car. The car temp is normal. The fan runs whether it's a hot or cool day. It doesn't matter ...

    Our Saab has a very interesting problem that the dealers can't figure out.
    The vehicle will start for several days then won't start, but sometimes starts with a jump, or if you waite a while it will start. (its not the battery) any body had this problem?

    Rough idle
    It's erratic when standing still with car running. Code says a misfire

      For the misfires

      It may mean that one or more of the following has happened:

      Faulty spark plug or wire
      Faulty coil (pack)
      Faulty oxygen sensor(s)
      Faulty fuel injector
      Burned exhaust valve
      Faulty catalytic converter(s)
      Running out of fuel
      Poor compression
      Defective computer
      Possible Solutions

      If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

      If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

      Check your fuel pressure regulator and fuel return lines. Seems like they may be clogged. Any codes coming up? Get those scanned.

    At stop signs and lights, the RPMs rev from 600-900 RPMs. Please help!
    After driving for a bit, the revving will stop, however, There is a 5 second delay from that point on, from pressing on the accelerator to actually picking up speed. It has stopped the past couple of days, but I bought a scanner to see what codes pop up. They are: ...

    I had white smoke come out of the exhaust, and I smell burning oil inside the car when I turn the heat on, is this related to the turbo

    Check engine like P0420, catalyst converter .
    While in school for automotive I decided putting a different muffler on my 2003 VW jetta 1.8t. Doing so I took out the resignator after questioning my teacher to see if I did so if it would cause any issues which in response he said it wouldn't or shouldn't so ...

      Removing a resonator or muffler AFTER the cat should not cause a P0420 fault code and if it seems it did it is a coincidence. Maybe though.....the resonator was causing slightly more backpressure and removing it lightened the back pressure but that would mean without any doubt in my mind that your catalytic converter was already right at the threshold of setting a P0420 which is for an inefficient cat. I suppose that is possible. It is the rear O2 sensor that plays a role in telling the computer the efficiency of the cat.

    My car suddenly will not turn over and my ignition key fob will not release from the centre console ignition.
    I've checked the battery and it's got power, even with a charger it will not turn over and the key will not release. The car only has 90,000km's and has been running fine. The last time this happened it was a very low - nearly dead battery.

      1. In the present no-crank condition, check for battery voltage at fuse 30 (dashboard fuse box) in the crank position , if no power there suspect ignition switch.

      2. Check for power in the crank position at pin 15, Blue wire, at transmission position switch connector (16 pins located under maxi-fuse box). If power at fuse 30 but not here, suspect transmission position switch.

      3. From there, power in the crank position goes to the activation coil of the starter relay to send power to the starter.

    Engine does not run hot but water bubbles out of coolant resevoir? What could be the problem?
    This happens when I turn car off. The oil light comes on when I stop at a light and sometimes the engine cuts off when I stop. There are 154,000 miles on this 1999 SAAB, 93, 4 cylinder hatchback.

      Make certain your electric radiator cooling fans are coming on properly at around 200-220 degrees. If not a radiator temp sensor or fan fuse or relay could be bad. This is the only thing that connects the dots in what your saying your problem is. As Oil gets hot it thins dramatically and can cause oil light to come on indicating low pressure.

      I'm not sure where you live but cold weather can trick you somewhat in thinking you don't have a cooling system problem

      Most common problem would be a bad thermostat or head gasket. The best way to start without paying for testing is to replace the thermostat and gasket and see if that fixes the problem.
