Hello Ecomodders!

A few months ago I purchased a faded red 1992 Honda Civic VX with 370,000+ miles on it as a vehicle that would get great fuel economy without doing anything to it besides a simple tune up and cleaning. I've had the car for awhile now and i've loved the fuel economy i've been getting.

I bought a vacuum gauge for it and I noticed that whenever the vacuum gauge hits 0, it starts to speed up alot faster. I assume this is the ECU changing the fuel mixture from a lean mixture, to a stoichiometric mixture. (If i'm incorrect, please explain why)

As the title of the thread says, I would like to make a switch that can shut lean burn off. This is my daily driver, and I do like to go on backroad cruises and have full power, but I also like to save my gas when driving from point A to point B. When I'm on a backroad, I don't care what I'm getting for fuel economy. I don't like when the vacuum gauge reads 5, and when i go to push the throttle more and it goes to 0, that speeds up really quickly. ( I assume the ECU is going back and forth from a lean mixture and a stoich mixture. It's just very annoying when all I want is power )

I know there are wires that lead from the O2 sensor that go to the ECU, and I'm wondering if I made a switch that stopped some signal going to the ECU, that the computer would just continue to run a stoich mixture?

Here is a link (http ://technet.ff-squad.com/wiring.obd1. htm) that shows ECU wiring and stuff, Connector D has the Lean Burn o2 wires, if anyone knows what needs to be switched, cut, ect. please let me know! Would love to make a DIY post for anyone else who may want this mod on their VX.
