I have my car jacked up ready to take out my O2 sensor so I can solder in my new MIL elims. Can i drive my car after I have unclipped my O2 sensors and taken them right out of the car? I just noticed i am out of solder and need to run to the store to get some. Is it safe to run the car? Or should i just put them in until I pick up the solder. I pretty much have them out right now and dont want to waste time to put them back in if i don't have to.
