      It is telling you there is a code in the computer . It's telling you something is wrong . Could be as little as the gas cap was not tight or something in the motor is going bad . Hard to say . Just have the code read to see .

      Have it checked for trouble codes. Some of the national brand autostores will check codes for free.

      Service engine soon means there is a fault with in one of the sensors that the engine control module monitors. It can also come on for emissions and misfires. If it runs OK more than likely it is cause by a evap failure. Which has to do with the emissions. Emissions are the control of gas fumes in tank. Some are emitted to the engine to burn. Some are venting gas fumes safely.

    Why does my car die when going around a corner at approximately 15 to 35 miles per hour?
    The check engine light is on and I had it checked. They told me it was a vacuum hose. Could this also be causing the car to die?

      Vacuum leaks definitely will cause the car to die and rpms to fluctuate. These vehicles also have 2 crank sensors that are notorious for causing stalling issues. Fix your vacuum leak first.

    Is it possible to have a bad serpentine belt if there appear to be no visual signs of damage?
    just bought this vehicle 5/6. Did not hear noise intially prior to purchase. Belt and pulleys seem tight and good working condition. I only hear it in when the car is cold or mornings. The noise isn't very loud, but noticable coming from the area where steering and ...

      It isn't a tapping type noise, is it?
      With any used vehicle, I give it a tune-up as quick as I can because usually, you don't know the date of the last up. Check all fluids, change engine oil and filter.

      If it is a belt driven accessory that noisy, You can take something with a long metal shaft, place the end of the shaft on the accessory housing, the other end of the metal shaft goes on that bone behind your ear, it helps to magnify the sound. Listen to each accessory housing in turn, see if you can pinpoint the noise? You just have to be careful, not to get yourself or the metal piece caught up in the belt or pulleys. Safety is your responsibility.

      If your worried about the belt, replace it. If the old one looks ok, keep it the trunk for a spare.

      What you could do is remove the belt when engine cold and see if the noise goes away when
      you start it. WARNING do not leave engine running longer than necessary. If noise is gone
      shut car off. Spin each one of the pulleys including the idler and tensioner pulleys and listen
      for the noise.

    My coolant level is up to where it should be, but the coolant indicator says to check coolant level.
    mileage 87,000-seems to happen while warm-it occurs while driving-i just brought the car-no check engine light- no other warning lights, except security indicator light. and thats because i hit the security keys on the door.

      the coolant sensor is in the burp tank its an on off switch i would say its bad but i would test it first. drain burp tank put your voltmeter to both wires with meter in ohm mode then add antifreeze if the meter changes the switch is good hopefully it doesn't. if you don't have a voltmeter unplug sensor light should stay on then jump the harness plug with a piece of wire light should turn off. if it doesn't its a wiring issue if it works to turn off the light then its just the sensor.

      It might be caused by a backfire condition during starting, although I cannot say why. But the possibility means that anything related to a misfire condition has to be solved. Look for fault codes that may be stored with a code reader to assist you.

      Are you referring to the tail lights not working - yet all other lights work OK? If yes, then the problem will be related to any of the following; faulty light switch, faulty / poor wiring connection common to the tail lights.

    I have to go through long crank time before the car gets started; what could be the cause/causes?
    the mileage is 149-150,000; the problem started after I had a new injector rail, wires and plugs put in, which lead to buying a new battery, then a new fuel pump; I still have the problem; I've been told opinions that it may be the crankshaft position sensors, which ...

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.
      Do not purchase any additional parts (including the crank position sensors) or service based on opinions - but facts. Facts which are as result of proper diagnosis and testing to determine the cause of these issues.

      The long start cycle may be result of; low fuel presssure (clogged fuel filter, faulty fuel pressure regulator) or weak ignition spark - but to determine if is this is the case - has the fuel system pressure been tested?
      The fuel system pressure should be within range of several PSI at the; outlet side of the fuel pump, to the filter, to the fuel injection rail at the engine. What are these system pressures during start-up?
