Unexplained Limp Mode

throttle bodies are often first to blame. whether it be due to sticky flap mechanisms or throttle position sensors which chuck a wonky reading.

i cant remember who it was on here that suggested out of sync throttle bodies as the issue. i've datalogged my throttle bodies and they're about as perfectly in sync as you can get them.

shfeddy - you have a supercharger kit so that adds another variable. but i think a fair few folks with tunes have experienced the random loss of accelerator response. this makes me think there might be one cell in their tuned throttle maps which the ecu doesnt like. hitting that cell would take a certain combination of inputs so it's hard to replicate. i'm still standing by my throttle tune - it's the same map that's been posted up on these forums and most folks have been troublefree so i'm ruling that out for now
