I bought my 09 cobalt about 4 months ago and within the last couple months I noticed sometimes when I go to pull out in 1st gear im giving it gas and letting out the clutch but it almost goes to stall out as if i wasnt giving enough gas and I have press the clutch in and start again. I then started to notice a hard hesitation or kick as im driving while maintaining a constant speed but only somrtimes did it do this. I brought it to the dealership and they said it was the MAF sensor along with a dirty air filter and dirty throttle body. I changed the MAF sensor and checked the air filter which was completely clean. After changing the MAF sensor the hesitation stopped for about a week and started again. Anyone have any ideas?
