When I fire my car up in the morning, I hear a very soft and irregular "puh - puh" sound. Idle is smooth. It almost sounds like the popping you hear on decelleration out a loud exhaust, but very, very subtle. It goes away after warmed up. Anything to worry about?
"puh puh" sound out of tailpipe

What would the cause be? Oh, and this is only at idle.

Autolites. Brand new.

ouch - are there any other symptoms of burnt valves - because it runs great and the sound goes away after warmed up and the idle comes down

Yeah - I think the 103s (my tuner put them in). What motorcrafts are you using?
right now I am using the stock equiv. but in the copper version. Supposed to be good for high hp application. I'll see if I can find the part number. I know they are the coldest ones available (they are the 12's I know that) by Motorcraft.
Follow-up.
After coming home tonite, I listened to it idle and was smooth. No occasional puh-puh - just sounds like a Borla with the occasional burble.
I'll check the plugs soon just to see how they're doin'.
