      Check for a bad ground. Not just the ones that go to the battery and alternator, also check wires that go to the engine and the vehicle chassis. They can be loose or rusted and corroded

      when you say it's full is that compressor running checking pressures with gauges or blowing a little out? turn the a/c on max check for power to the a/c clutch if you have power check your gauges if it pulls a vaccume og gets below 20 psi on the low side either you are low on 134 a if there is no power find the low pressure limit switch see if it has continuity through it from there check the fuze for a/c . if there is a restriction with it running feel the lines where it goes from hot to cold is the restriction but usually a chunck of the compressor is what is causing it.

      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.
