Re: check engine light (slim689)
What code was it throwing?
If it WAS the O2 sensor, it should clear after a while. How long? It's not just miles, it's drive cycles & more. If the new O2 sensor doesn't fix it, it'll keep throwing the code.

i know it was the o2 sensor code for sure
ok but heres the thing....i hand tightend the new o2 sensor into the cat because i didnt have a wrench....it was in there pretty snug, but if by some chance its not tightend enough would the code just stay on and not go away

The O2 sensor actually measure oxygen DIFFERENCE from inside vs. outside of the exhaust pipe. Exhaust leaking out over the outside of the sensor will throw off that measurement. It takes awhile before the CEL turns off, but I think the code remains stored. It's not a set number of miles or a set number of start/stop cycles. Its a combination of lots of things that have to be satisfied before the readyness codes are all set.
Tighten the sensor properly.
Have someone read the code & tell us the number.
Reset your ECU.
Let us know if the CEL comes back.

Re: check engine light (JimBlake)
Ok dont guess that you have a oxygen censor code. Actually find out what it is.
Second of all go and get a oxygen censor socket and tighten it up.
You can rent the tool from autozone for 15 bucks and you get a full refund when your
done.
If your car is a 96+ then you can go to autozone, schucks or anybody who does free
testing and asking them to scan your codes. If its older you can find in a manual
how to check it your self.
