When I started the car the service engine light came on. When I drive around 20 mph at a coast without making any changes in pressure on the gas pedal, the tachometer hovers at around high 2000 to mid 3000 rpm. Normally in this type of scenario, my tachometer will read 1500. When I start to speed up/push the gas all the way in, the tachometer jumps to 3/4000 rpm and just hovers but doesn't really move. Then the car feels kind of jerky so I let off the gas. I didn't want to keep the gas all the way because I didn't know if the engine would be further damaged. I'm just worried if the transmission is bad or if its something further wrong with the car.
What makes this problem better or worse?
Car feels a little like its vibrating
