Again, when it rains it pours!!...now bad throttle switch?

[L DC]

An update on the situation. Yesterday, I left the car
home and did not drive it at all until I checked
things further based on your responses; thank you.

After work I looked around for air leaks, without
taking anything apart (I know that's just superficial)
and found no leaks. Also took off the zip-tie of the
throttle switch I had placed to get the car going
after sputtering and loosing power last friday on the
highway.

I started the car and it fired up nicely on the first
crank.

What the heck??

I proceeded to disconnect the O2 sensor while engine
was still cold but idling and nothing happened--still
kept idling nicely.

Then, I plugged the O2 sensor back in and when car got
warmed up I disconnected it again and nothing
happened--still idled just fine.

I drove the car to work this afternoon and it ran
beautifully with no issues the entire trip: 57 miles.

Knock on wood; I have to drive back home at 7:30PM

So what's the deal??

Thanks again,

Louis
