I am sorry my first post is a help needed, i have a problem with a L8 ecu car, it has an uneven idle it hunts a bit but not massively, when the car is revved the revs stay at around 3k, i have checked for vac leaks and none are evident, if I unplug the iscv the revs return to normal also if I remove the tps plug the car also returns to idle, the tps is a pf09 set to 0.35v throttle closed, from what's happening i am presuming the tps is faulty, it has a new ect sensor, act sensor, 3 bar map sensor, phase sensor. I have also given the iscv a clean just in case

I am ready to pull my hair out over this car
