Drumroll..... it was a horizontal map sensor that bit the dust... reading up the forums that was one of my thoughts, however most people said it failed after some major backfire which I haven’t experienced... luckily it’s a cheap fix! Definitely wouldn’t of been able to diagnose that at the track... Sent from my iPhone using Tapatalk
Seems like an easy fix at the track. Take the vertical map sensor and corner low to make it work like a horizontal map sensor.
