I got code 136 and 116 today.

136 means "HEGO sensor circuit indicates system lean (left side)"

116 means "ECT out of self test range 0.3 to 3.7 volts."

But what does those mean in dummy terms?

Dude I got a 136 too! along with a 412 and 172 that I'm trying like hell to figure out. I hope your problem is easier then mine!!!

116- this sounds like your have a bad Coolant Temprature Sensor; front of the lower intake manifold.

136- heated oxygen sensor indicates lean condition, left side.
