My Z started acting funny, it was idling weird and when i gave it gas every now and then i would get no response. Service engine light came on and i ran a code test and came back as P1122: electric throttle control system performance failure. Ive done a good bit of researching and cant find a correct solution. It has a turbonetics single turbo with a brand new throttle body. could be a sensor or relay or whole system, not exactly sure. im an auto body guy, I appreciate the help!!

I don't know much about FI, but that sounds expensive. Good luck.

Was the problem happening before the new TB?

It was replaced, along with other parts, when the turbo kit was installed.
