the air sensor will do as you say when disconnected. this engine can do
as you say with all kinds of things going on. check for bad sp plugs,
bad sp plug connectors, vac leaks, etc. might wanna check and see if
you got oil on the trigger points. most trouble shooting will start with
what is the major symptom. is the problem spark or fuel relasted??
