Default Re: another p0300 question

small update... took my sut to the chevy dealer near bye to get it scanned. they said it is misfiring on numbers 2,7. and that 7 seemed to be the worst.They recommened a leak down test to check my valves... i understand a valve could cause some of my issues. But what are the odds of valves going in both heads same time? I left while the scan was still free...

so has anyone had a similar problem?
