I own a 2007 350z and recently changed changed the injectors with a new pair of oem injectors. After putting everything back together and starting the car for the first time, the car started to freak out. It started to rev randomly and uncontrollable. Then it seemed to calm down after warming up but then immediately started going into limp mode. I went ahead and scanned the check engine light and got 4 codes. P2101, P2132, P0228, P1239. The misfire code was already on the car before installing the injectors. The new codes all seem to be related to the throttle bodies. I checked the connections to the throttle bodies and they all seem fine. Throttle bodies are fairly new and in decent conditions. I did still check and see if they were dirty and they looked fine. I don't think they are bad because the car was acting normal before I changed out the injectors. I am already aware that the 07s have sensitive throttle bodies and I have already delt with idle surging in the past from touching the throttle bodies. I fixed the idle surging a while back by getting an 08 ecu. Please help. Thanks.
