need more help with bank 2 richness

im still so depressed. i put so much effort into this car.

i already changed the O2's, wires, plugs and cleaned stuff out.

when i reset the battery to clear everything, it'll run fine for about 4-6 drives. then all of a sudden my CEL comes on. so far (the two times i've scanned it since changing the O2 sensors) i've had p0175 (rich in bank 2).

first of all, what can cause me to be rich in one bank? my guess is a bad/leaky injector. im letting it drive more with the CEL on just to see if any more codes come up.

car drives fine. idle is perfect and the power is all there. no hesitation. just that CEL. how can i go about solving this? any info is greatly appreciated.

im going to flip-flop the injectors after i scan it and see if the problem is in fact the injectors (if it is the code will show up on the other bank). that is if i dont see a plug that is darker than the rest.

any ideas?!

and what happens when a rich code is found? does the EEC lean it out on that bank? or does it do nothing?

I'd check the injectors or just get new ones and see if it helps.. otherwise check your tune.. fuel pump???

how much are new/newer injectors? how would my fuel pump cause me to be rich?

hehehe. thats exactly what the problem was! (this is an old thread). i actually modified my chrome one and it works much better now. turns out the metal tube was actually sitting inside the maf housing!! i shortened it and modified the iat seat some and so far no problems. the tube is definatly shorter than the stock one now.

here's my thread
