2009 Aveo Bucking/Jerking/Losing Power

[HeavyDuty]

My 2009 Aveo did this also, just be driving along and nothing then would restart..no lights no warning and it would also just quit sitting in the driveway running or when you went to back up just die. It did it for a year nothing was ever found and it hasn't done it lately....I am thinking it hasn't done it since the OEM plugs were pulled out and I stuffed the boots with dielectric grease...so I will back Doax's play here....do you happen to hear rather large spark arc type noises through your car's speaker system ? I use to get those all the time, I had to disconnect the satellite radio and that stopped...which was about the time I had the first plugs changed so I did two things at the same time there not sure which one made the stalling stop. I submitted a safety concern complaint to transport canada about the unexpected loss of engine power and subsequent loss of power steering while this was happening because I was unable to turn the corner the last time it quit, but got lucky it caught before I hit the curb.....sure scared the daylights out of those daycare kids though....sidewalks not so safe after all !
