[QUOTE="OldmanBM, post: 340742, member: 4576"] ICV most likely. ICV also rarely damaged. You should try to remove ICV, it has a connector which you remove by depressing the C clip beside the link housing. Then remove the 2 allen keys bolts. When removing ICV, pay attention not to damage the gasket. Remove gasket. Spray WD 40 or petrol into the two openings of the ICV. Let it drain tru. Use sofy bristal brush to dislodge any dirt. The clear wd 40 which is clear will flow out brown in color. Clean as best as you can but take care not to use force on the ICV metal valve inside. Fix back. YOur engine should be purring like a cat ! [/QUOTE]
