Ok, I know it means fuel delivery system, but what could that include? I made sure that my MAP sensor works fine(I unplugged it and my car ran like ****, plugged it back it, ran like a champ.). Could it be an o2 sensor maybe? or what else? My fuel pump seems to be working fine(no whines.) My car tends to run really rich too.. and it idles high.

 

bump for response

 

could be an o2 sensor.....is your car bogging at idle or acting wierd?.

 

Besides idling fast, not really. I think its a tad bit slower than what it should be due to it running fairly rich.

 

TIm, i just got the same thing today myself...but the thing was my CEL never came on i closed looped it to do timing and 43 cams up..werid! im trying to trouble shoot it now

 

my guess would be an 02 sensor

 

I had recently gotten my valves adjusted from a reputable acura dealer 2 days later my car throws a cel code 45 (system too rich or lean) so i brought it back they said it was running too rich and they checked everything 2 hours they had it. Turns out I'm getting leakdown through one or more of my injectors. Just somthing to think about. waiting till spring to spend the 200-300 in new injectors
