Started out with code p0411, replaced parts got different codes after each replacement last codes were 0411, 0171 and 0174. Brake booster was leaking badly so mechanic replaced and cleared codes, after thirty miles engine light and driving symptoms came back including smoke under hood.
Previously changed in order, EGR, purge valve, secondary air injection check valve, and vent vac. Each time engine light and driving symptoms came back after twenty to thirty miles of driving. Out my wit's and money.
have the same problem?
