Thanks for the info. Mine did not have the yellow warning light come on - instead it was the engine management light. Also, the engine rpms did not blip like the one you show. Mine stayed constant at around 2100 rpm and when I rolled the throttle, the RPMs increased but it was obvious there was only one cylinder running.
I am curious - the fault code said throttle valve 2 initialization. Did your fault code also say the same thing?
Lastly, what does it take to change the throttle valve - cost, part nu,bears, etc. if you know...thanks again
