SOURCE: i have a code p2096, post catalyst trim system too

put a new rear O2 sensor and it fixed it. Only problem you might have is if you have an aftermarket downpipe. If it is Catless then you are going to need some type of tune, opensource, Cobb AP, etc.... Even if it is a high flow cat then you will still need a tune because it will throw a code 75% of the time. If your stock cat is still on then replace your rear O2 sensor and that should fix it. Could be something else but mine was the exact same problem.

SOURCE: I have an 08 Saturn Astra XR. It won't come out of 1st. Throwing code p2096 post catalyst fuel trim system too lean bank 1. Put on new o2 sensor on both streams and I cleaned out mass air flow. Help?

That code wouldn't cause it not to come out of first gear . How did you retrieve this code P2096 , code reader etc.. This is an invalid code , not listed in Saturn service information . Have DTC'S check by a GM dealer , Chevy . You obviously have a transmission problem not an O2 sensor problem . Some code readers will replace a code with an other if it doesn't have the right one . Software .
