Hey guys, first time posting here. I've had my m35 stagea for about 6 months now (250t rs our) and i absolutely love this car. ever since about the start of last month it decided to enter limp mode on me. since than i have replaced a lot of parts. Started with plugs and coils and that fixed it for about a week, then i moved onto cleaning the intercooler piping and tb, same thing happened as it was fine for about a week then started going into limp mode again. then replaced the throttle body, maf and accel pedal position sensor and did all the relearn procedures. car ran good for almost 2 weeks! and well this morning on my way to my morning college class it wouldnt even leave my driveway without entering limp mode. I'm honestly at a loss with this car and not sure where to go next with it Can anyone think of anything else to diagnose? i dont have a scanner of my own to check the dtc's when it enters limp mode but im working on getting one. to clarify, my stagea is a 2001 with 124000km on it. always maintained properly in my ownership as well.
