I purchased a used vehicle. When I bought it the CPU had been reset and I was unable to get it smogged (emissions tested). When the CPU finished its cycles I got it tested and it failed. Mechanic said I should replace the EGR Valve and the 1st O2 sensor. I did so and it failed again. Then they said to clean out the Exhaust Manifold. I did, it was not very dirty, and it failed again.
How probable is it that the CPU, having gone through its cycles with the bad O2 sensor and EGR Valve, is causing the test failures since it is running off bad readings?
