I have a 93 accord lx that has a check engine light issue. When I start it up there is no light but when the engine comes up to temp the light comes on and it idles very low at that time. I removed and sprayed out the EGR valve and PCV valve was replaced to no avail. The issue is there is no stored codes in computer so when I go to read the flashes there are none. I'm stumped

 

You should be able to jumper the SCS connector while it's running, so that way you can wait until the problem shows up.

Then you should probably make a new post with the error code, over in General Tech. That's where the "real" tech. questions belong. This is a kind of welcome & introductions board for new members.

 

And Welcome and Thank You for joining.

 

Is it running any worse? Rough idle? You may have a bad O2 sensor.

 

As Jim stated, don't guess. Get the code, then test.

And yes, thanks for joining.
