Forgive me for posting without complete info. I have had a random issue of late with one bank being rich. I will pull the codes again when I get home but going from memory as it has happened a few times. It seems to happen early in the am after a cold start in 40 to 50 degree weather. I will leave home drive a short distance and be in 2nd and light seems to come on when throttle is closed. Usually after a minute or so it goes back out, has been staying on longer. When it first occured swapped what looks like oe oxygen snesors. Now it is happening a bit more regularly and today the light cycled on and off even at fwy speed and warmed. Any thoughts as to what can cause rich short of a leaky injector. the fact it is only one bank makes me lean toward an injector (s) but open to hear more.
