Hi Everybody, I've never needed to replace an O2 sensor till now. It ain't coming out. Spent nearly a couple days and the only progress I've made is discovering what I would have done to engineer a better system.
The car wouldn't idle in gear without a slight power brake manipulation.
Unhooked O2 sensor and now I don't need to keep one foot on brake & one on gas to idle in gear. I've used a torch and a wide assortment of tool combinations to get the sensor to brake free. Now the hex on the sensor won't hold a socket without slipping.
At this point I'm down to figuring I'll leave it in for now, braze up the top to stop an exhaust leak where the guts/wire of the sensor broke out and fool the ECM into thinking the sensor is working (see below).
Surely someone has done this too. I was hoping for advice on the best way to rig a variable resistor up to the single wire going to the ECM. That way I could fine tune the fuel to rich or lean according to what I want for any senario; and I was thinking this would be beneficial to maybe injecting hydrogen and I could adjust the voltage for a leaner gas mixture for that purpose without a MAP enhancer???
It's on an '88 Regal -4 speed auto - 2.8 liters - no room to get a straight shot at the sensor or turn a tool against the firewall for a solid bite.
Any advice welcomed to steer me into a better direction. If I pull the engine or slightly hoist it at some future point, I'll replace the sensor unless what I'm thinking works better for my purposes.
