Just changed both front o2 sensors. now i get a code p 1141 load calculation cross check range/performance; P 11 27 long term fuel trim b1 system too rich; and p1129 long term fuel trim b2 system too rich. WHAT DOES THAT MEAN? ALSO CAT & EVA are blink ing when im reading these codes.
PLEASE GIVE ME SOME GOOD ADVICE ON HOW TO FIX THIS ISSUE SO MY
CAR RUNS BETTER AND PASSES SMOG. THANKS[/COLOR]

 

Saw some post this on another forum regarding the p1127/1129 codes:

My mechanic pulled this list of items to check given a p1127,29 code.
1. MAF Sensor
2. O2 Sensor Bank 2 Sensor 1.
3. O2 Sensor Bank 2 Sensor 2.
(check all O2 Sensors)
4. Fuel Pressure, Regulator.
5. Fuel Injectors.

Since you changed the o2s it could be the MAF.

 

Thanks ill try that

 

After changing parts how do i reset the check engine light cide

 

With either a VAG com or an OBDC reader. Autozone will pull and clear the codes for you as well.
