Aveo 2008 Jerking/going idle and jumping

[tajyana]

Hey guys,
I bought my chevy aveo 08 about a year ago and it now has 68,000 miles on it. My check engine light came on and my car is starting to jerk a lot. About every few minutes when I’m driving and I don’t know what could cause it and don’t think I should drive it. The code is P<100, has anyone had similar issues or know what it could be? Also should I not drive it before I go to the mehanic

has the timing belt been changed?

I'd check to see if the air inlet tube is cracked and dried out.....it will allow too much air in and cause the jerking/surging you speak of.....maybe thats it.....get the part from a dealer.....aftermarket is wrong.....or get a junkyard part. Hope that helps ya.
