Driving my STANG
i just installed a new 70mm throttle body and spacer and a new 76mm mass air meter. Start it up. Rough idle. And check engine light with codes 34, 67 and 85.
Car was running fine before install.
I cleaned EGR and IAC, still rough idle and CEL still on.
When I drove it, there was a hesitation when I hit the gas.
Any information anyone has would be great.
Thanks

34- EVP- either a failed EGR sensor or bad ground. Do you still have the EGR attached
85- cannister purge valve- Do you have the charcoal cannister?
67- Nuetral Safety switch failure-yes this can cause a rough idle. is this an auto or stick or AOD/stick conversion? Did you depress the clutch when running the codes?
