NEED HELP!!! CEL w/ Multiple Codes!

[PaulHuntzy]

Hi everyone I still have my Tahoe but my 2002 Chevy Silverado 1500 pickup 4.8l is currently undrivable!

So my truck has 157k miles and was running extremely well until a I tried starting her up last week and it was fielding really low and stalled. After around 3 tried it finally stood started. While driving I noticed a big loss in power and when in WOT it only goes up to around 2500rpm and won't accelerate and I hear a popping noise. But if I slowly accelerate it can go up to any speed I won't.

NOW.... a few days later it won't even stay started at all. It stays started for a few seconds and just idles really low and rough and just stalls, every time I try starting it. I tried cleaning the MAF sensor and that didn't help at all.

And of course there are check engine light codes. And here's the list of them

P0174 (fuel trim system lean - Bank 2)
P0171 (fuel trim system lean - bank 1)
P0137 (HO2S-12 - Bank 1 Sensor 2 - Circuit Low Imput)
P0300 (multiple cylinder misfire detected)

If anyone has any experience or help to offer it will be highly appreciated!
