Occurs at startup and on and during acceleration; sitting.

So far - moved car to WV where ethanol gas is really bad. Shortly after first tank: over-heat and white smoke. Pulled the vacuum hose and no fluid and sucked on it and plugged with my tongue and it held and could pulled no fluid into the hose. I drained, flushed and replenished the collant and it seems to hold its level. Pulled plugs and no water and none blew out upon crank without plugs.

Seemingly; I have eliminated trans fluid and anti-freeze being blown out the exhaust.

Next: would a plugged cat converter do this from bad gas?

There has to be a source. O2 sensor affect???? What am I missing? What checks can I make?
