Hello i have a 2004 nissan 350z with 182xxx miles and i took it to the shop to get a fuel pump replaced and after it was replaced the car wouldn’t go above 1500rpm, I assumed it was the throttle body and threw a 75mm throttle body on the car and that didn’t fix it either, so i asked the shop to take a look at it and they came to the conclusion that the throttle control motor wasn’t getting power and that there was no Wires in pin 103, 104, 105 he said he looked at schematics all night and they all said the same thing he had told me it would work with a switch added that i’d have to turn on and off with the car itself , He kept blowing fuses and gave up on me, codes are p1122 p1126 p0123 p0223 Any help is appreciated
