Hi, when I start the engine after a while ( not immediately may be when the engine getting warm) flashing the engine light and at the same time running the engine sluggish and vibrating. Throttle body , mechanical flap making snap movement with light noise.
no faults code appear, nothing. I changed spark plugs (new) , I changed , ignition coil (second hand but which are working)
still the same... any idea what can be?
Thanks
