MY 98 neon will start run for a couple of minutes then lose power and stall. It will turn over but won't start for 10 minutes. I was told it is having 02 sensor problems could i just unplug there electrical conection to the 02 sensors and let the pcm run on default settings would this work if it dose could it cause any major problems in the long run? Any ideas. The car has 300 000km and I don't wan't to dump much money into it.
