Q: Throttle

asked by on October 17, 2016

my car was jerking one night, and the "change oil" light came on, so i got an oil change. after a while, the car jerking repeated once again, and the rpm's were in the red. now that i let the car sit, it's finally back at rest at 0, and at below 1 rpm while idling, i drove it around the block, hit 50 mph and the throttle seems to reset just fine. is my car safe to drive?
