As you can see in the title I have a p0345 code. I have replaced the camshaft sensor because I had the code but the car was running fine except maybe the tiniest bit of power loss, until one day on the free way my throttle fully went out no matter how hard I pressed down car did not accelerate in rpm’s. I pulled off to the side and the car woikd only accelerate to 10mph and 1,900rpm I drive it home and turned the car off and on and it was fine and so I changed the connector for the sensor and now my car takes 5 seconds to start and there is noticeable power loss. I did order an oem camshaft sensor from z1 because the one I replaced is from hitachi so could be a faulty sensor or I made a wiring mistake can anyone help me out to figure out the issue. I highly doubt that it’s a timing chain issue as my miles aren’t that high I don’t think that it could be timing chain. 114k miles 03 350z mods done intercooler, oil cooler, trans cooler, plenum spacer, intake, and test pipes and a tomei.
