O2 sensor

Hello all. I haven't posted here in a while but after some good times drunk driving, past parking tickets, stolen tools, and suspended licenses, i'm back in my saturn with the cylinder head and valve cover replaced, a new APC titanium muffler on the way (only paid $50, wow!), and a new ect installed with the coolant light still flashing, but more importantly, my SES lit as usual. the codes if i remember correctly are an 0133, 0140, and an 1133, all of which are related to the O2 sensor in some way or another according to chiltons. What should i do? If it makes a difference, i have the 92 headers on my car but don't know if the mechanic used the 92 sensor (came with it) or the 97 sensor. Thanks for your help folks!

I assume you mean low coolant light, If the coolant is low toppoff, if not smack the jug a few times (the floats hang from time to time, flush the system if coolant is nasty especially if you put the head on due to oil in coolant. O2 sounds like either the old sensor was used or contaiminated from chemicals (used during clean process) ir missfire.
Just a couple of places to start

yeah i'm guessing it got contaminated; my old valve cover was cracked but repaired via glue when i replaced my head but it didn't really have a proper seal on the right side so oil sort of, i dunno, "drooled" through the gasket and down by that area.

the 97 O2 will not thread into the 92 header, O2 sensor bung changed in 95

sweet so i guess it looks like i'm stuck with a SES either way; i guess that's the price for doing mods to your car. Oh well, this is the best the car has ran ever so i can live with that. :bigthumb:
