I hope you don't mind if I jump in on this thread...

I have an OBD0 hatch and don't get a CEL right away, but I eventually get one (Code 1) after driving on the highway for 10 or 15 minutes. I'm working on getting a new O2 sensor, but I starting wondering, "what if that's not the problem?" The car has absolutely no mods with 190,000 miles. But basically, I'm either running too rich, too lean or my sensor is going bad. Is that about right?

Re:check engine light
 

Most likely the sensor if you have no mods...

thats exacly what happens 10-15 miles after I reset the ecu cel comes back on with the code. So what do you thimk about when I hald the gas steady and it gaining and dropping rpms.everything was fine until I swaped injectors

Re:check engine light
 

so if the light doesn't come right back on when I reset the ecu could it be that the sensor is getting cloged up
