Pulled the codes...

[bruce988jl]

Alright i'm new to SHO's and just ran the CEL code test today and these are the codes that i pulled. NOTE: both tests, the car ran a "system OK" the following codes are the ones that were stored...

157 (R,M) Mass Air Flow signal is/was low or grounded – MAF

172 (R,M) Oxygen sensor not switching - system is or was lean - Single, Right orr Rear HO2S - Fuel control

173 (R,M) Oxygen sensor not switching - system is or was rich - Single, Right orr Rear HO2S - Fuel control

176 (M) Oxygen sensor not switching - system is or was lean Left or Front HO22SSS - Fuel control

177 (M) Oxygen sensor not switching - system was rich Left or Front HO2S - Fuel control

217 (M) Primary circuit failure - ignition coil 3 - Ignition Systems
The Coil was replaced last year, so i'm not sure if this is a stored code... BUT one of my cylinders is not working when i'm driving...

543 (O) Fuel pump monitor circuit shows no power - Power / Fuel Pump Circuits (M) (Service 556 code first if present) Fuel pump relay or battery power feed was open - Power / Fuel Pump Circuits

I talked to my friend who said i need new O2 sensors.. which i probably do. And for the MAF fix he said to clean it with brake cleaner. But my car is running on 5/6 cylinders (the one closest to the driverside front of the car isn't running when the car's engine is on), and i was wondering what could cause this problem... but all the spark plugs and wires are working fine (i tested them)

Thanks a ton in advance,
Jason Lee

EDIT:
I ran the cylinder balance test and it gave me the following numbers in this order: 2-3-4-5-6. I'm assuming that cylinder # 1 isn't working right?

try resesting your computer first before you just to any
conclusions,reset it and drive it around for a little while
then run the codes again,this will erase all your stored codes

alright i'll do that first thing tomorrow and see how it goes. Thanks for the response. I'll post up the results when i drive for a day or two.
