On the way home from work today I NLS from 2nd to 3rd and did it without error after continuing to drive 3 miles i came to a stop and suddenly the car started to miss and sound like it was back firing. The CEL flashed and when i hit the gas it got work with no power. I read the codes of p0300, p0303, p0304 and the a horrible sound coming from the motor. Any idea guys???

 

I have had same issue with mine but I have the 2.2 engine power reduse light comes on and sound like 3 cylinder if I run it hard did not figure out the issue tho but I disconnected the battery for like 15 secs and it runs normal hope you figure out what's wrong with your balt
