Re: ask about...a problem with my buick lesabre 1994
Yes, the oil should not be up too high on the indicator. To see what the service engine soon is telling you go to a Checker Auto, O'Rielly Auto Parts, or any other auto parts store that offers free automotive scans and they will tell you why your light is on. If the person whom is performing the scan is nice you can ask them to clear your codes. Fix that oil problem ASAP!

It could be anything, but fuel pressure is down on the list. Look for vacuum leaks, dislodged hoses, cracked hoses....much more common for problems there.BUT take the car and have the error codes pulled. Something is amock and the codes are clues. Not answers or the culprit necessarily, clues...
Does this have a "Check Engine" or "Service Engine Soon" light on? If so, get the codes pulled and post them back here along with the engine info. If no codes are present then it may well be a bad crankshaft sensor. I have seen many of these give intermittent problems (usually heat related) and do exactly what you have described without setting a code.
If the service engine light is on, it could be a faulty sensor or anything electronical with the car. It may even be something non noticeable. The only way to check exact problem is to run error codes.
the service engine soon light means a fault has occurred in the engine or emission system's electronic controls, it has nothing to do with any service you did in most cases, there are over 150 problems that turn the light on, to find out what the problem may be go to any Kragen Auto or Autozone parts store and ask them to run a OBD 2 trouble code test, IT IS FREE. then post the code back here for us to look at, which is also FREE.
I found several shops in my area, Albany, NY that had the older code readers. It worked fine, and cost me $30.00. It showed a bad O2 sensor that I replaced myself. I suggest you go to a reliable shop. Auto Zone/Advance etc.. do not have the right code readers.
