I am tryin to fix my car; I originally had the gear 1 incorrect ratio code I managed to fix that. I changed my transmission filter, I changed my fuel pump, changed my throttle position sensor, mass air flow sensor, ignition rotor. I am tryin to get my car back on the road. After I changed the throttle position sensor, changing my transmission filter and adding more transmission fluid; it started not going past 3000 rpms. That is when I changed my fuel pump assembly (just did that today) and it still won’t rev past 3000 rpms. I need help if someone can help me that’ll be much appreciated thank you!
