Has any one had this problem?

Hi all,

while my car car is waiting to go to the body shop I thought I'd ask for help to figure out this problem:

when I start the car first thing in the morning
it will run rough for about five or six seconds before catching and running smooth. It seems almost as if it's getting poor ignition voltage,
since the idle sounds 'Weak'. This started shortly after winter.

Any ideas?

O2 sensor possibly

Plugs/wires could be suspect as well.
Idle issues are the ISV...clean it up

Re: O2 sensor possibly

Can't be the 02 sensor, it runs open loop during most of the warm up (at least the first 20 seconds).
