Hi GUys,
Its probably a ditry AFM or plugs or o2 sensor, but best for you professionals to determine
Past couple of weeks noticing random flat spots through the rev range, still have power, just rpm sits for abit before climbing again.
Just started the car, drove it this morning with no worries, very ruff idle, black smoke starts belowing out. stopped the car and started again, perfectly fine, no ruff idle, no smoke. No mechanical noises can be heard ie knocks etc
any ideas?
