jerbear!

i tried searching but couldnt find much info. im currently running with no o2 sensor on my 93 del sol. is there any advantages/disadvantages in doing so?

Built to Spill

no advantages....just disadvantages. o2 sensors are good..i would recommend putting them back in.

the richness of your fuel depends in part on the feed back from the o2 sensor, along with temp, and oil pressure, if you take it out your car will go into a safe mode brought on by your ecu. If you dont want to use your o2 the get a new ecu. The safe mode map that the ecu uses sucks and you will loose power.

Yeah, what he said. The year of your car doesn't matter, its the ecu inside. If your car requires O2 sensors, you must use them. I use a PR4 in a 99 Civic, so I don't need any O2 sensors.
