I patched it. I had two codes ....but now those codes are gone and i have the one new code

I would triple confirm the repair to the EGR pipe before buying a new O2 sensor.

+1 on this! Hold off on the sensor until you check this.

U guys think i should do another smoke test to confirm...?? If i have to buy an o2 sensor which one should i get...??

NGK and Denso are just as good as AC Delco replacements... just not as pricey. Stay away from Bosch.

Unless you already did a smoke test after the repair, I would do one.

I ordered an o2 sensor from rockauto but wouldn't u know before the part got here the light just went off on its own but i guess if it comes back I'll b ready for it......i also ordered rear control arm bushings and both front control arms...wish me luck...Lol.

Let us know how the front control arm bushing replacement goes.

The front control arm is an easy swap...not hard at all..20 mins tops a nd i put a denso o2 sensor on my car hopefully the light stays out....
