The car is a 99 GSR that was recently rebuilt with 100 miles put on it. I normaly drive it to work and back wich is a 5-10 min drive during these times the car runs and idles fine with no warning lights. When i take the car on longer trips and the car gets warmed up the oil light begins to come on at idle. It also begins to ildle very low almost sounds like it will stall when i take off the accelerator. After a few minuites of the oil light flickering on at idle the oil light will continue to flash on and off.
