Help!!!! Car stutters and engine light on

[Pedraza202]

Hi guys am new to the forum and need help. I have a 2009 chevy lt aveo 5 (the hatch back version) the other day I was driving on the freeway and my car stuttered for about 4 seconds like it wanted to turn off and went away. The next day it did it again about the same speed (60-65) but this time the service engine light turned on but went away after. Today my car did the same thing but this time the car stuttered, service engine light turned on and then the hold light was flashing and the engine light was flashing and wouldn't go away this time. When I came to a complete stop the hold light went away but the ses light stayed on . When I turn my car on now the ses light stays on solid and the car stutters on idle. I don't know why this is happening the car has 48,000 miles. My car is original no modifications made and is automatic. I don't think it's my transmission because the car runs just stutters like it wants to turn and shakes. The cars idle rpm shakes up and down. I dont need to give it gas to stay on but does stutter. Please help guys its my only car and I need the problem to go away soon. Someone told me maybe it's the maf sensor or maybe the air sensor . Please help

what maintantence have you done so far? Sounds like a tune up is needed possibly if not already done

had the same problem i'd see what the code reads at auto zone. and go from there heres what i did.
i replaced map sensor. thermostat. and cleaned the o2 sensor. but i had warrenty and i did not kno this at the time. u better see if u have powertreain warrenty and take it in.

also 1 of my vacuum lines came off on the top of the engine and if it gets cloged it shut off. it started right back up tho

Tune up has never been done that I know of. I got the car certified new at a chevy dealer. Sadly the car is no longer in warranty I think 36000 is the last of it. Would a tune up fix the problem. Is it possibly misfiring.

it sounds like a misfire to me. the hold light has been on in a few threads here for coil pack issues. but not everyone posts the results of the issue. I know there is an rpm signal to the automatic computer from the coil pack though, and a bad coil pack would cause this running condition (as would bad plugs, which i understand are to be changed @ 24K) So i would start with replacing the plugs, and then check the condition of the coil pack once you have it pulled out.

Powertrain warranty is 5yr/100K miles

[ontarian_frog]
