Not sure how to explain this. I did a search and couldn't find anything. Our 2012 Cruze LS/RS 1.4 is acting up. No codes so can't really pin point it. Just that when my daughter drove it she said it was jerking some going down the highway at times when she gave it light throttle to pass.
I took it out and what I have noticed is that it will jerk/buck some, not much but it is kind of like it has a miss in it, but only noticeable in manual drive in 5th gear. When I shift down to 4th and run the throttle, either lightly or hard it doesn't do it, same in 6th, but seemed to do it when in 5th.
It does it in drive but I wanted to narrow it down to see if it was gear specific and it seems to be only in 5th for the most part.
If you go out and start at WOT it runs fine all the way up to cruising speed.
Again, no codes/CEL, could it be a bad coil pack or one going out?
I played with it for about 30 minutes and it didn't get any worse. Plenty of power if you are at hwy speed and punch it, no noticeable jerking. Just seems to be happening under light throttle conditions.
Anyone else with these symptoms?
