Well car continues to have same problem

Appears to be link to after the car is hot.
Had an tech 2 scanner on it today and every thing seems normal. Unfortunately I am an idiot and never did the case learn but at this point im thinking this is not the case.

Ltft were 3 and stft stay about 0

Knock retard when the car was wot was 3

When the car began surging the mv for the front o2 were jumping around.

Car has white residue on exhaust tips and pulled a plug and was pretty white.

Car seems to run lean during sputter

Car ran fine when cool and wot had no problems smooth.

Just changed plug wires
When problem occured unplugged
Maf sensor problem not solved
Unplugged o2 sensor problem not solved

Could this be
Icm or coil pack?
Or dredged lim gasket?

Car does not seem to do it if hood open and just idle
