i have a trouble code coming up it says miss in the #1 cylinder. I have a slight puffing sound thru my exast. If i clear the code it will trip the check engine light by just idling in the driveway. My friend says its a leaky injector. what do you all think and if its a leaky injector how hard is that to fix.

What year and engine? Fixing leaky fuel injection on a CPI is common but different than later years :)

Dumb question... have you tried the obvious stuff and replaced the spark plug and inspected the wire?
