Ba XR6 TURBO idles high, engine light then revs go very low and makes knock sound

[Redberries]

Cold started my ba XR6 TURBO the other day after a few days of sitting. Revved up to 2000rpm then engine light came on and revs dropped down to 500rpm and began to choke itself out

It will have logged a Forced engine shutdown and a TPS error , few things could of caused the issue but this is a typical TPS issue, they become faulty over time
