Assalam o Alaikum
Hello everyone. I am a regular reader of Pak wheels forums and i am really thankful to all of you as i solve many issues without asking through your discussions.
I have Toyota Corolla Indus with 4age 20v bt swapped engine. When i bought this car the wiring was not complete and engine was running on safe mode (or whatever it is called) due to incomplete sensors input. Oxygen sensor, air temp sensor, thermostat valve, tps calibration, cel ,ac idle etc everything is now complete except for vss input to ecu which is a trouble for me right now. As soon as we connect the input signal wire to ecu (sp1) car start jerking on low rpms. Not continuously but it can happen anytime. Once i cut the wire car runs smooth again. Please if anyone can help regarding this issue.
