i have code 1 after i put in a new o2 sensor and a dc header.Is this damaging my car in any way, of am i just losing power and running richer.I have the header with the o2 bung at the bottom near the cat.I don’t knwo what to do or where to go to get this fixed.now i hear i would be better off getting the 92-93 o2 sensor because it has 4 wiers and because the bung is at teh bottom it’s reading off all four and not just one.Would that solve the problem?Does anyone else have a header on a 90-91 whtih that bung at the bottom with no engine light on.Should i go to a mechanic or a muffler shop to egt it fixed.Been having this trouble for a week and don’t want to throw away money.Any and all help is appreciated and thanks too
All that code is telling you is that your O2 sensor is either bad or not working right. And you probably are running a little rich because of it.
First off, you cant use the obd-1 O2 sensor because it wont work. You have to use the 1 wire one.
When you installed that new header and extended the wire for the O2 sensor (if you did) did you make sure to SOLDER the wire and not crimp it??
You should be able to fix that problem without the help of a mechanic pretty easily.
Good luck and let me know if you need anymore help.
Later,
