Hi guys!

Two or three month ago I diagnosed a bad AOS on my car, not serious, but enough to trigger the check engine light.

I replace it with a "URO" AOS, it worked fine... until today.

I have to check fuel pressure and vacuum lines, but there's 99% chance that it's the AOS again, the CEL came on in the same conditions.

Otherwise, the car runs perfect, idle is good, it's got power, revs happily.

Long term fuel trim is at +1.6%
Code P1128 and P1130

My question is, do you think my cheapassery is the cause here? Or something else can cause the AOS to fail prematurely (I can't figure what would)?

Thanks!

Ben
