running rich

[jderry]

why does my car run rich?
i get bank one and bank 2 rich codes
i have brandnew O2 sensors in it

[Darren]

how is it running? when is the last time you gave it a tune up?

[jderry]

plugs wires and coils have less then 400 mles on them
oil has about 75 miles on it

so recently

it seems to be running decent
but these codes dont trigger a SES but they come up on the scanner

[Lucky SOB]

dirty MAF sensor?

lol my car is a 6

there are many reasons it could be running rich. to start i would look at the freeze frames, write them down, then clear the codes and see if they come back.

Yes if they are good try those no sense in buying another if you have acess to two others...

[jderry]

im thinking it may be the plugs

so im going to do that
espically after it seeming almost as it was missing
