E3 Spark Plugs, anyone?

06 Cobalt Rough Idle/Stall when stopping or quick deceleration

seafoam problem
You're supposed to let it stall with seafoam to soak the heads. It's not unusual for it to be hard to start for a few moments while full of seafoam. Sea Foam Usage Video I've "fogged" several vehicles and never experienced a problem with them.- deadbird
