SES after G3

Markar97 · 03-21-2013, 10:38 AM

Roy's Z - Did you ever resolve your P2A00 issue? I have been getting it after my CAT back system install (have G3 installed also) and it keeps coming back. Was having issues with this code previously after warranty engine replacement (oil consumption issue) and reinstallation of my G3, but thought is was resolved (dealer replaced A/F sensor 1, bank 1 and when code came back they replaced the exhaust manifold gaskets). Had no issue for several thousand miles, then just recently put on Cat back exhaust and the codes keep coming back. Looking for answers. May try the MAF cleaning. Not sure i was tracking with exactly how to do the by the book learning procedure above. Note that prior to the engine replacement I had the G3 installed for 6 months with no codes or issues at all.

Might be a MAF sensor on the blink, may need replacing. If you installed HFC's when you installed the catback exhaust, then you need a tune. Last, it may be an exhaust leak in the catback ( possibly a gasket) not being torqued down enough.

It appears that I am getting these codes due to the hfc's I have on the car. Dealership told me that my car is running 127% which is extremely rich! And also I noticed it while driving the same way I always do, a lss in mileage. I also tried cleaning maf's and it didn't help any. Im getting multiple random misfire along with the p2a00. All should be fixed after my tune In a few weeks.

So just as an fyi for myself. If I run a cbe, keep the cats and install a cai with no tune. Will I throw a cell? I know I shouldn’t be due to having the cats and have had other cars with this type of set up. But I’m reading a lot on the Z getting cells after G3's? Any insight would help.
