Only once or twice this has happened before... Seems like the engine/exhaust is sputtering under throttle, driving, or revving while stopped. Also a noticeable lack of oomph. Each time, it seems to have corrected itself, more quickly if i kicked it in the *** and revved it hard a little bit. This last time, i had left a light on inside for about a week and killed the battery apparently, so i jumped it with the Hyundai and started it up, let it run for a bit, then took it for a drive to let it charge up right. I noticed the sputtering, and figured it would go away... half hour of driving later, sputtering still there .. what gives? Any ideas? My guess would be spark plugs..?

 

Ohm injectors, check plugs and fuel filter, check CAS connector.etc

 

check all your connections to the injectors and stuff. I had this issue and it turned out one of my injector plugs had cracked and it would randomly slide off just enough to occasionaly cause a sputter. check electrical connections first for corrosion and good contact.
