Oil check light flickering below 1,000 RPM?
I'm driving ford Taurus SES 2002. It will ONLY happen after driving for about 10 to 15 minutes. Once the engine is in idle ( below 1000 RPM ) it will start flickering and sometime just stay on until I push the Gas pedal.
It started right after I changed my oil for the first time after bought the car (Jan 2014). So I changed the oil couple of months ago and about 1 week later it started acting like this. I brought the car to the same mechanic and they told me it's because of the oil pump (after investigation). I called different mechanics and they say different things, like they said it might be because of bad oil filter that they installed (NOT craft). So I took the car to the lube stop and after checking the oil filter they said it was so loose and I had lost half of my oil. They fixed it and had it tight, pure some oil to the engine. I thought if the problem has been solved but after driving for about 10 minutes the problem came back. I changed the oil pressure censor with my friends car and I still have the problem!
please someone help me figure this out.
