Hi everyone. am new to the forum and would like to extend my warm greetings. I have a nissan hardbody 2.4 16v. Have replaced throttle body and now the vehicle does not reach top speed. it drives ok, but only on low speed. It first had an issue with stalling, but tha was resolved as it had an open circuit on the relay for the fuel pump. I can only get to 100km/h and nothing more. If anyone has had the same issue or have advice on how to resolve the issue, i would gladly appreciate it.
