The od light keeps coming on and flashing but took to garage and computer says nothing wrong also after that happens then the seveice engine soon light comes on not to go out until reset computer by way of battery disconnect ???

take your car to auto zone or any parts store that will run the check engine light test for free. See if they can pull a code telling you what is causing the light to come on.if there is no code no one can tell whats wrong until it reappers if this is helpful please leave good feed back

It sounds like the oil pump stopped pumping.. that's unfortunate. Because if it did. And you took it to a shop. 9 times out of 10... they will want to rebuild the motor. And I'm sorry to say.. but the best thing to do is to get out from under that car.. because everything is TREMENDOUSLY expensive to repair.

must have a scanner to reset light but it will come back on until you fix the problem have the system checked to get trouble code that will let you know where to start

Your garage mechanic should have reset the light, take it back to them.

If the light was flashing when it came on, then it means your engine is misfiring.

A solid light can mean anything from a loose/faulty gas cap to a transmission issue.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially turn on.

Start buy spending $30 dollars on a speed sencor attached to the top of the differential that should remove the OD flashing light and the ABS Light also fix the speedo not sure about the service engine soon light that could be many other problems..Good Luck!

blue smoke on startup is generally from worn valve guides or bad stem seals on same (not really terrible as long as it stays the same) It will run rough for a minute 'till the oil in the cylinders is cleared out. Service engine light is pretty much on its own timer and does not mean anything but it's there to annoy you into going to the dealer. If O2 sensor was bad, it would eventually put the red check engine light on.

replace the 02 sensor and the light will go off.

There is something wrong, they may not have had the correct equipment for your car. Even if they had the right scanner and it said nothing....means there is something wrong if the light is on. The computer doesn't put that light on for fun. I would try somewhere else, a lot of auto parts stores will check it for free.
