Recently replaced the OVP and ran a 2 91 Octane tanks with Seafoam treatment. This helped a little but the problem still exists.

Run Down:

I start the car in the morning around 5am it takes 2 long crankes and it normally starts.

Upon start up, she idles real rough and I need to press the accelerater pedal to keep her running.

After i push just a little gas, she picks up and the idle clears up after a few mins... almost perfect very very slight miss.

(All of this these steps she is in park)

If i sit there for another 2 mins in park the rpms will very slowly creep up to around 1500.

I push the accelerator pedal to the floor and the RPMs stay the same. (sometimes they decrease to slightly under 1000)

Then I put the car in either Drive or Reverse the RPM's lower down to 600-800 rpms and idles with a slight miss.

Anyone have an Idea of what I should look at for?
