91 crx problem

hi I have a 1991 Honda Crx that i have put some mods on to. Know i am
getting the error message on my ecu that it has an oxygen content
problem. I thought it might have been the Cat. so i changed it but
that did not help. i would greatly appreciate it if any one can tell
me how to fix it.

 

Care to post the actual code? That would help us help you.

 

also a list of the mods u put on it?

 

i have put a cold air intake, a full exhaust, msd spark plug wires,
and a proformance module. i don’t know the code all i know is the
light on my eco fashes once and i looked that up in my chilton and all
it said was oxygen content

 

I might have missed it in your post but would like to know the exact code
that you are referring to. If you don't know the exact code, visit Auto
Zone or some other auto store that will determine your code (for free).
Most of the auto stores now offer this service--for free. In most cases
"oxygen content" means that you need to replace your oxygen sensor. It's
fairly easy to do on most Honda vehicles.

 

thank you that is wat i was think but i wanted to have another opinion
before i spent the money on a new sensor
