      just change the oil and put the cap back on you will be fine. if you don't live on a dirt road i would just top the oil off and run it. the smoke is just the oil burning off of stuff if you worried hose it down with a can of engine degreaser.

      First thing is to check the oil level. Do this after the car has been shut off after 5+ minutes to get an accurate reading. It is possible that oil was shot out through the fill cap, causing it to drop on things such as the cylinder head and/or the hot exhaust manifold. If you replace the oil fill cap and drive around and still see some smoke it may be due to valve cover gaskets leaking....but usually unlikely in a car as new as yours. Check cooland level and search for any leaks

    Why does my car smell strongly of gas fumes when I start it?
    This happens when the car is cold or has not been running for at least 6 hours. Regardless of outside temperature. No check engine light is on or any other warning lights. Continues to smell like gas inside and outside of the car while it's running for several ...

      Can this cause a fire?

      The risk of fire damage would depend on if there was a fuel system leak - and where it may be located.

    My car will crank but wont stay running.
    I replaced the ECM and brought it to Chevy to have the ECM flashed. I forgot that it has a 2000 enging in it . Would this make a difference?

      it doesn't matter did you replace the ecu because it wouldn't start or did you replace it and then it wouldn't start? if not starting was the original problem i start y determining if it is missing spark or fuel issue. if you just crank it a little smell the exhaust if it smells like gas it's more than likely a spark issue. if it's a fuel issue listen for the fuel pump if it sounds like it is running and the engine isn't geting fuel buy a fuel pressure test kit best money i ever spent for a 3.8. if its spark look how to ohm check the coil packs. youtube is great for stuff like that. and how to test cam and crank sensors.

      I replaced it because the fans would keep trying to come on when car shut off and clicking noise in fuse box. I replaced the fan relays and MAF sensor. The car would crank but l had to pump the gas pedal. The service engine light wouldn't come on until second start. Also the security light was always on.

      i see you need to re calibrate the ignition for the security system. it is something you do you cycle the key for somany seconds i have to go to work but you can find how on youtube. good luck

    I changed all motor mounts and the motor still shakes
    Not as bad as before but still a lot of vibrating
     
    • alex
      10/19/2014 alex
      a little vibration is normal a lot of vibration is coming from a miss carefull of being zapped pull one plug wire at a time all of them should make it lose rpm and shake if one doesn't that is the hole that isn't firing. start by pulling the plug if it looks bad start with a tune up if a tune up doesnt fix it change the injector if you have a compression tester check compression before the injector. anything after that is a mechanical failure a vavle, rings, cam lobe.

      Need more details to help you out. Is this shaking only at idle? Freeway driving? Does the speed matter? Does turning left or right make any difference? Does this shaking occur when accelerating, or turning on components such as air conditioning or headlights? How about your gas mileage or any check engine lights?

    Why does my vehicle back fire and die after running about 45 minutes
    My suburban will run fine for a short time. After about 30 to 45 minutes you can gas on it a little and it back fires and dies.

      The most common cause of overheating is because of an external leak from a water pump or a radiator or heater hose. The way to find the leak is to wait till it is overnight cold and maybe just pour water in and see if the leak is large enough to see it simply leak out from where it has a leak. if you pour in a half gallon or more and you still see no leak its time to pressure check the system.

      Here is a short list of possible causes for overheating;

      Low coolant level
      Leaking coolant
      Improper coolant concentration (not at recommended 50 / 50 mix of anti-freeze and water)
      Clogged radiator hoses
      Clogged heater hoses
      Clogged radiator passages
      Clogged heater core
      Faulty thermostat
      Faulty water pump
      Faulty radiator cooling fans
      Faulty radiator cooling fan switch (coolant temperature sensor)
      Faulty / worn serpentine drive belt
      Faulty / worn drive belt tensioner

      DI'd you try testing the battery with a load tester?

      the battery is brand new less than 6 months. We started to have this problem around the same time last year just as the air was getting a little cooler since then we have replaced the fuel pump the fuel tank the water pump the radiator the air charge temp sensor battery terminals and have cleaned any corrosion seen. Nothing helps. she ran great in the summer time she would sit for a week and I would go out an now that it's a little colder out I have try three times and even then she may not go
