I've been teaching my friend to drive stick on my Subaru 2004 Impreza Outback Sport, and the gas was a little sticky/crunchy, so it was hard to give just a little gas. It was either none, or a little too much.
I used a general automotive spray oil to lube the pedal, which didn't help, so I lubed the springed throttle mechanism under the hood where the cable from the pedal attaches (proper names for all of these things would be a nice bonus to an answer to my question -- what are all these parts called?).
This fixed the problem initially, but now that it's like, 0 degrees outside, I find the throttle even stickier. Not crunchy like it was before, but if I step on the gas, the rpms will stay high, even if I've let off the pedal.
This problem does seem to go away when the car is warmed up. So, Im thinking I used the wrong kind of oil, and it's seizing up in the cold?
Any recommended fixes? Could I degrease and relube these parts in a better way? Maybe this is just a general problem with the cold?
