So my tezza was running perfectly fine a little while ago, and then it all went downhill. When it's cold it seems to run okay but when it's up to temperature the idle is all over the place, even ti the point where it will drop down so low and stall. (which has happened multiple times)
The only thing that has changed is my flywheel to a solid one, and when I was in the engine bay, I knocked the coolant hose to the throttle body thermostat and broke the hose connector off. So at the minute I've just bypassed the thermostat by running the hose from the inlet straight to the outlet on the block.
Would this be the cause of my problem? I have seen people say that when the thermostat is dirty it can mess up the idle and make it all over the place, so that makes me think it's that.
I've tried everything else like clean the maf (and even swapped it for my spare one with no effect) and reset the ecu.
And help would be awesome
