Do you have any cracks in the intake? Is the VAF connected. I don't know if it will run after it warms up without the VAF, but sounds kinda like how mine ran when I forgot to hook VAF up.

Maybe a head gasket problem that seals when it is warmed up? I'm just throwing out ideas not trying to scare you.

Instead of the CEL, you can connect an LED between FEN and GND in the diag box, to read the codes.
