2013 Chevy Spark LS Manual - Problems when accelerator pedal isn't pressed

Maintenance/Repairs
1

Hey everyone, my spark has 32,340 miles on it. I’ve noticed after driving for periods of 20 minutes or so that it has been having issues once I need to stop and maybe even feather the clutch in tight traffic. So basically if I have to stop and go it will lurch/lunge/jerk forward AND backward and continue to do this until i’m finally just accelerating all the way past the tight traffic.

I’ve read that it could be the engine mounts, fuel system, air intake, cat converter, all sorts of things. This car has/had a known issue with its PCV valve and a misfire on cylinder #4. They were recalls and were done, it then later had an issue with a misifire on #3 and then all the plugs and a coil were replaced. So it has no more issues with a misfire. What do you guys think it could be? Thank you.

I think it might be a dirty throttle body. Have it cleaned, or clean it yourself. It isn’t hard, lots of YouTube videos on this. Try that and report back

And tell us if the check engine light is on. If it is, have the codes read at the auto parts store and post those exact codes… not what the counter guys says they mean… the actual codes, and we’ll go from there.

I have my own OBD II scanner, it doesn’t have any codes. I know what a throttle body is and that mine is electronic controlled. I just wouldn’t have suspected something like that having build up with only 30k miles on it.

Only 30k miles but 7 years. Thst means short trips and greater possibility for buildup.
