I was merging onto the highway and floored it and the gas pedal stayed there. Little scary. Kicked up the gas pedal manually and it dropped to around 12-1500 RPM. I limped it home like that replaced the throttle cable. That seems to have helped but it still won't close 100%. The spring to the left and lower on the throttle body seems stretched or something. It's still in one piece but kinda bulges out in the middle and feels funny. Is buying a new throttle body the only option?
