Sounds like I burned my o2's right? Had ran the car with an open y pipe for a month and these codes come on and off. Car idles a lil rough and jerks at low rpm not too mention it feels like it got its ***** cut off. Seems like it loss power.must be since the computer isn't reading the o2 right?any help will be appreciated.

Car has long tubes

You will need a scan tool to look at the fuel trims and see if they go above 23%, P0171 & P0174 set if the PCM detects a excessive lean condition for more than 6 seconds. You will also have to see if the if the o2's are fluctuating between 200-800 mv. If they are than you either have a vacuum leak somewhere or weak fuel pressure.

+ 1 Check fuel trims. I really doubt 2 o2's would go bad at the same time. Sounds more like a vaccum leak to me.

Checking the fuel trims and o2 parameters like I mentioned before will indicate bad wiring or a true lean condition.

very common to see a dirty or bad maf to cause such codes, u can start there if you do not have access to a scanner.

I had the same issue when I got my car, was fine when normally driving but when hammering on it CEL would come on. Fuel trims were fine normally but when hammering on it both sensors went lean. Hooked up a fuel pressure gauge and sure enough pressure was dropping at WOT at around 3k RPM.... Stock fuel pump couldn't keep up anymore...

I have a fuel pressure gauge (shitty one) you can hook up and tape to your windshield if you want to check it (I'm in Vista/San marcos)
