Hey guys

Any Help will be great ...

I got this code PO133 the "02 sensor slow to respond. (bank 1 sensor 1)."

Primary sensor and its gotta be shot. Right?

I also pulled this code P1129. "Manufacturer controlled fuel & air Metering"

Guessing this code (P1129) is caused by the faulty 02 sensor?

Is it a good idea to replace the 2nd 02 sensor at this time? got smog this year.

yes its been running poopy. i thought it was the map, did the wack when it originally acted up, before i got the codes.

also the spark plugs look as if shes been running a little lean.

the S is an 03 w/ 27k miles on w/ comp T supercharger after cooler.

Thank you

 

Hm thats strange. Usually when an 02 sensor dies the ecu makes it run pig rich to keep you running safe. You don't need to replace the secondary sensor if you don't want to, if its working its working.

 

Do you have a TP as well?

 

P1129 is high MAP signal.

 

Hi...

Ridestrt- i thought so also, ill ck the plugs again mabie things have changed.

Marlins- nope, no TP here, live in the nazi state of CA. They'll hang me!!!

Billman - would it be best to buy a new map or just beat it again? Also what do you refer to as high? it just reads high and it needs a reset?

thank you for ur insight
