Got P2119 code, help please...




I was driving on the fwy yesterday, and as i was exiting and slowing down, my car started shaking and my check engine light came on. I pulled over, restarted the car and it wasn't shaking anymore. As soon as i got home i checked the code and got "P2119 throttle actuator control throttle body range/performance & P0304 cylinder 4 misfire detected" What does this mean?
I cleared it and drove again. Same thing happened when exiting the fwy. Today I drove around all day and it didn't happen. Any ideas?
Thanks...




Anyone know what needs to be done???
