Hey guys!

Not sure if im posting in the right thread and all. But lately ive been getting the shittest idle. revs from 1300k - 1400k rpm just bouncing up and down. Car is tuned to VAFC2 and you can see when i put my foot down on the throttle around 4% car doesnt move just revs then anything past that it goes, and also car is just **** to drive car just jerks and everything. already have replaced tps to another OEM one. But i was thinking if i do put a new one on like the Blox one or so, do i need to recalibrate it and so on?

Thanks!
