Code P0175

I keep getting this code whenever I am decelerating and making a left turn. Any ideas on what could cause it. It has happened twice so far. The truck still runs fine. Any info would be greatly appreciated.

p0175 fuel trim system rich bank 2
bank 2 leaky injector
faulty ho2s bank 2

And it only happens when I'm running the A/C.

Well today I got the code again and I got the same code for bank 1. It seems to happen on sudden deceleration. I also forgot to mention that it has a rough idle. I was thinking of changing the plugs, pcv, air filter, possibly the EGR. Any thoughts would be greatly appreciated.

although that would be good maintaince, i do not think it will fix the problem, it sounds like a leaky injector or injectors, maybe you can try running some injector cleaner through it.

I have the same code on my 97 Tahoe. Tune-up didn't help. I changed both oxygen sensors located before the converters and I still have a service code. Mine also idles rough with AC on. Someone told me to check the fuel pressure with key on but engine off. If low it may be a leaking regulator, but I haven't purchased a gauge to check it yet. Let me know if you fix yours and I'll do the same.

I have 2 codes for lean bank 1 and 2? Same deal? I have had work done on a pressure regulator around the tank area and fuel filter under manifold replaced? Didnt do a thing.

Just checking to see if anybody has found the cure for this code. Mine is intermittent. I can't even get it to do it. Just when I figure out how to duplicate it, either it won't duplicate or happens when I least expect it.
