Default Can Any of these codes decrease my performance?

I have a lid, ptb only stock ls1 trans am.

Today i was driving the car and it felt more sluggish then before. As i went WOT today "check engine" light popped up.

3 codes:

p0101
p0137
p0157

can these be the culprits to my sluggish acceleration? thanx.

The other two are rear O2 sensor codes, they won't.

I agree, address the P0101 and then re-evaluate performance, that's most likely the cause. A sudden change in weather can also effect performance.

As I understand it, this particular decision is important. From what I've read, the SLP MAF and the Granatelli MAF are both supposedly junk. Not speaking from personal experience, but yah... if it comes to it, stick with OEM.

Can anyone else confirm my statement? I mean just to serve as a heads up for folks who stumble on this thread while doing a search on these codes in the future.

Where do you go to look up codes and learn about them?

Check your wire harness plugging into the MAF, and its wires. I fought MAF problems for a long time on my old 97. After about my 4th MAF sensor I decided to trace the wires. Sure enough the yellow (12v) power wire to it was frayed and barely hanging on. Bought a new pigtail for like $8 and spliced it in. Problem solved.

Just a thought, might wanna check that before you buy a new MAF.

Just type the code in in Google. You'll find results.

since the day i signed up on the Tech, i constantly saw threads on Aftermarket MAF sensors... And in every thread about them people say to steer clear of them because it would be harder to tune the car after more mods... Plus the hp gain is virtually unnoticable, i'll stick with OEM thanx, add a hundred dollars more, and buy a set of Ebay LT headers...
