only a theory but if the temp sensor was dangling down near the head / exhaust temperature area then itd go high and maybe its a safety that it does turn off when intake temp is super high???
we needa know if it has a temp sensor or not lol
my mate had a v4 i think it was and it did have a air temp sensor which was in the air box standard...someone did the mean "churr bro" pod install and left it dangling in the engine bay... i drilled a hole in the kneck of the pod filter and put the temp sensor in there and it ran alot better and alot better fuel economy
just a idea anyway
