Friends,

Yesterday, my check engine light came on and stayed on. I read the codes...had two, 2-3-2 (fuel trim, too lean or too rich at idle) and 2-4-1 (EGR system flow too low). I experienced no performance issues; the car idles and runs fine. This morning, I cleared the codes. The check engine light went out had has stayed out. This afternoon, again with the check engine light not illuminated, I checked the codes again. I got 2-3-2 again, but the code 2-4-1 did not reappear.

So, to repeat, the check engine light is not illuminated, and I am still getting code 2-3-2. Any ideas? Vacuum leak? "Lazy" O2 sensor?

Thanks in advance,
