Hello

I've got a few questions about the fuel system on my 85 Model B230F with LH 2.2
fuel injection.

As gas prices soar, I like everyone else am looking for ways to increase fuel economy.

Presently I'm experimenting with a few ideas that I have, and could really use some information from a few of the experts on this forum.

I've been driving and working on Volvo cars for 37 years, but I am by no means a expert on the fuel systems and their performance characteristics.
I've always done the "plug and play" when fuel problems have occured, so I've never really dug into the specifics.

My questions are specifically.

If I unplug the Oxygen sensor, will it cause the fuel system to run lean or rich?
Would there be any adverse reactions?

Does this system use a engine temperature sensor as a input to vary the fuel mixture?

If so, what happens if I unplug the Oxygen and Temperature system at the same time?

Is there any way that I can "trick" the computer and cause it to run a lean fuel mixture?

Like I said, I'm experimenting, and if any of my ideas produce results, I will post them here for all to see.

Thanks for any response
