I have addressed all of your ideas including changing the oxygen sensor and the car still surges on cold start. This seems to happen when the ambient air temp. is below 60 degrees but not above. Local tech insists the injectors or a injector is leaking since there is a fuel smell when this happens. Any more thoughts ? Replacing injectors is a a big $$$ item and just want to be sure. By the way no fault codes.
