similar problem
I was on my way into work this morning going my normal route and when i was in 5th gear going about 60 mph I went to accelerate (pushed petal close to the floor) and my car started to jerk. I have a '01 EX manual with 41k miles on it.
I came to the same conslusion that my clutch is going, or a spark plug/wire going bad
I wouldn't think that the clutch would be bad at only 41k???
What you guys think?
