Why does my car do small littlt jerks when driving?

Check your mass air flow sensor. My 01 Chevy impala did the same thing and I bought a new sensor from Amazon and it runs like a champ now.

For anyone else reading this: I have a 2008 Impala 3.5 that had this problem; it would idle a little rough, it jerked when applying throttle from start occasionally and it would hiccup/stutter randomly in low ranges of certain gears (40-45 and 70-75 mph). Recommendations included MAF (I replaced), clean throttle body (I did), new Throttle Position Sensor (TPS replaced), new spark plugs (replaced), and evap canister (replaced). Nothing worked. Before these changes my mechanic checked it on the diagnostic computer and it showed a rich Bank 1 code (cylinders 1/3/5). It wasn’t until I changed the ignition coil that everything went back to normal. $40 bolt on part; simple. I have seen many people complain about this problem with the 2006-2008 impalas and yet no one ever figures it out. Hopefully this helps someone.

I have a 2009 Blk SS Impala /5.3 303hp, that’s loaded. Let her seats, heated seats, Bose system for perfect sound & a car that WILL GET IT! I got it brand new. It now has 120,000. Ive got it in a Dealer Shop looking at my car. My car will hiccup/cut out when I accelerate & on Hwy. some times when I take off at a light , it jerks into gear.?? So worried!! Waiting on my diagnosis of my SS & the cost!! Oh my! If all these people have the same problem- it should be covered by GMC CHEVY. Would you think? I a 90 model & it jerked too. Got rid of it b4 what Im going through now.

Maybe it’s the ignition coil .
