Please O Please don't use a Fram on that engine... Use the proper filter for that motor...

For now I'm holding the gas pedal to the floor and crank the engine for 2-3 seconds before letting off the gas, allowing the engine to start.. The reason for this is that it allows the engine to crank at a slower speed WITHOUT starting. Since doing the longer cranking times, the chatter isn't occuring upon cold starts.
*holding the gas pedal to the floor while cranking disables the fuel injectors + ignition.

How hard is it to change out the oil filter to rule it out? sounds like the filter could be draining back...
Cheap enough to check out?

I'm going to try and replace it tomorrow. The oil filter is located directly on top of the engine, directly beside the oil fill cap. 
Your theory is the same as mine Jr. Here'* a link to the cadillac thread I posted. I don't think they're on the right track at all.

I think after what you have described the oil has to be draining back when it shouldn't be.. And it sounds like the Valve train goes a bit dry till the oil is there.... With you doing the Pedal to the Floor to cut the Fuel and Spark... It sounds to me like you are getting the oil to move so when you do start it the oil is there..
So I do think it will be a cheap check for you.. Won't hurt..

I put an AC Delco filter into the CTS so I'll have to wait it out and see if the chatter still happens. Already the engine seems to run a little smoother though. The irony of the whole thing is that the delco filter cost HALF as much as the fram!!
